For my fellow javascript devs:
var floored = 12.68 | 0;
Is much faster than:
var floored = Math.floor(12.68);
And in both cases floored === 12

When you don't have new feature to add to the app but need to keep updates.
"General bug fixes and performance improvements."3 -
As you all know, I test a multi-million dollar product on Internet Explorer running on Windows 7.
Today, I have been assigned a performance testing task.
There are 20+ tabs open on Internet Explorer which takes eternity to load and if a tab is switched the entire page loads all over again.
You talk about having a hard day, eh?
I have been struggling since morning to complete one vanilla flow. SHIT JUST DOESN'T WORK.

The worst part about being a web developer is when clients ruin a perfectly good website by asking for dumb things, even though you told them it's either:
a) near impossible
b) not useful/helpful to users
c) deprecated/no longer used code/techniques
e) will harm performance and SEO
d) just plain stupid8 -
Today I learned the hard way that losing your app's key store means no more updating , bug fixing , performance boosting , features adding ...
The app had like 5k downloads on the play store ..
Lost the key when one of my hard drives burned ..

I recently got mailed by our support department.
A customer using my program experienced performance issues after updating the whole system; attached is a video recorded by the customer clearly showing the difference.
I watched the video: the old version took 20 seconds to load. The new version 26. After querying the data, it's shown in a list.
The updated version showed 61 datasets instead of 6 in the old version.
I asked the supporter if he even watched the video and he answered: sure, and I'm able to see the performance issue!2 -

My first performance review as a graduate:
Boss: "we can't give you the rating you deserve because HR"
Me: "ok whatever, what can I do to get the rating I'm suppose to get?"
B: *lists job description of a senior developer* ... "Interview candidates, mentor juniors, start a project and make me profit"
Me: (if I can do that as a graduate, what am I doing here?)
My last performance review at the same company:
B: "we can't give you the rating you deserve because HR"
M: "ok what can I do to improve?"
B: *lists everything I did before the first performance review that wasn't expected of me*
M: (LoL funny, I just wanted to hear your response because I know you'd forget about the first review. Another reason to validate my resignation) -

Has anyone looked at the linux kernel 1.0?
I am amazed with this! And the comments are priceless
e.g:
tcp.c
/* I hope this returns what I want. */
return(~d+1);
buffer.c
* 14.02.92: changed it to sync dirty buffers a bit: better performance
* when the filesystem starts to get full of dirty blocks (I hope).

To me, it seems like the rise of distributed systems like mesos / kubernetes combined with Docker require you to be master sysadmin, veteran kernel hacker and a part time c developer ALL AT ONCE if you really want to shave off time from debugging/ performance tuning sessions.

Worked with a European consulting company to integrate some shared business data (aka. calling a service).
VP of IT called an emergency meeting (IT managers, network admins) deeply concerned about the performance of the international web site since adding our services.
VP: “The partner’s site is much slower than ours. Only common piece that could cause that is your service.”
Me: “Um, their site is vastly different than ours. I don’t think we can compare their performance to ours.”
VP: “Performance is #1! I need your service fixed ASAP!”
Me: “OK, but what exactly is slow? How did you measure their site? The servers are in Germany”
VP: “I measured performance from my house last night.”
Me: “Did you use an application?”
VP: “<laughs> oh no, I was at home. When I opened the page, I counted one Mississippi, two Mississippi, three Mississippi, then the page displayed.”
Me: “Wow…um…OK…uh…how long does our page take to load?”
VP: “Two Mississippi’s”
Me: “Um…wow…OK…wow…uh, no, we don’t measure performance like that, but I’ll work with our partners and develop a performance benchmark to determine if the shared service is behaving differently.”
VP: “Whatever it is, the service is slow. Bill, what do you think is slowing down the service?”
NetworkAdmin-Bill: “The Atlantic Ocean?”
VP got up and left the meeting.2 -

When I was a young boy and I was writing my first programs, I remember I was sad because they were fast, unlike other applications I used daily and admired, with their long splash screens and the hard drive constantly making noise whenever you performed an action. At that time for me, 'slow' meant 'serious'.
It's fun to see how things have changed today: ensuring performance is a critical part of my job, and DAMMIT WHY HASN'T THE WEB PAGE LOADED YET?!?2 -

Our team was having a problem with very slow response times from a 3rd party web service they were contacting to get some device stats. No issues on the other end, but it had already been weeks. They ask me to take a look at it.
I take a few days, do a couple of benchmarks and tests and I isolate the section of code responsible. Turns out, the method they were calling would timeout if the device was offline. We ask the vendor, and they confirm this. They tell us to call methodX to check if it was up.
After having done that, lookup now only took seconds. They were annoyed that it wasn't documented but was just glad it was fixed.2 -

It fucking pisses me off when people compare experience as a benchmark of his performance or knowledge while hiring for job and even salaries depend on that. How do you know that, that guy has jerked around while the younger guy with less years of experienco would work better and harder.

Rant!
Been working on 'MVP' features of a new product for the past 14 months. Customer has no f**king clue on how to design for performance. An uncomfortable amount of faith was placed on the ORM (ORMs are not bad as long as you know what you are doing) and the magic that the current framework provides. (Again, magic is good so long as you understand what happens behind the smoke and mirrors - but f**k all that... coz hey, productivity, right?). Customer was so focussed on features that no one ever thought of giving any attention to subtler things like 'hey, my transaction is doing a gazillion joins across trizillion tables while making a million calls to the db - maybe I should put more f**king thought into my design.' We foresaw performance and concurrency issues and raised them way ahead of the release. How did the customer respond? By hiring a performance tester. Fair enough - but what did that translate into? Nothing. Nada. Zilch. Hiring a perf tester doesn't automagically fix issues. The perf tester did not have a stable environment, a stable build or anything that is required to do a test with meaningful results. As the release date approached, the customer launched a pilot and things started failing spectacularly with the system not able to support more than 15 concurrent users. WTF! (My 'I told you so' moment) Emails started flying in all directions and the hunt for the scapegoat was on (I'm a sucker for CYA so I was covered). People started pointing in all directions but no one bothered to take a step back and understand what was causing the issues. Numero uno reason for transaction failure was deadlocks. We were using a proprietary DB with kickass tooling. No one bothered to use the tooling to understand what was the resource in contention let alone how to fix the contention. Absolute panic - its like they just froze. Debugging shit and doing the same thing again and again just so that management knew they were upto something. Most of the indexes had a fragmentation of 99.8% - I shit you not. Anywho, we now have a 'war room' where the perf tester needs to script the entire project by tonight and come up with some numbers that will amount to nothing while we stay up and keep profiling the shit out of the application under load.
Lessons learnt - When you foresee a problem make a LOT of noise to get people to act upon it and not wait till it comes back and bites you in the ass. Better yet, try not to get into a team where people can't understand the implications of shitty design choices. War room my ass!3 -
Hmmm, this feature that I added seems to make the whole process 50% longer. I need to optimize something. Let's see now...
Yeah, make that a shared resource and parallelize IO to leverage the multi-core architecture. Hash map for this, binary tree for that. This thing that gets called a million times can be written easily without a regexp. That thing can be rewritten in Rust as it's too demanding.
There! Works! And it's also a lot cleaner. Nice!
How's the performance doing? 70% longer.

Have a query that runs in 01:58 and returns 517860 records. Rewrite it a bit for performance reasons, try running again, now it runs in 01:17 and returns 517870 records. Where the hell did I pick up those extra 10 records on that many total records?

I'm a graduate developer with 1 year experience. Was asked to improve the performance of a feature which was written by external consultants on £1000 per day, and in its worst case takes 2 hours to complete. I rewrote it and got it down to 1 minute 27 seconds.

I'm a perfectionist and like things done the right way, but had to learn to let go and remind myself it's the clients site and their choice.

For whatever ungodly reason my containers library, which has extensive testing, profiling, and benchmarks against other containers libraries receives regular emails directed towards me about it, always one of two things
1) "don't reinvent the wheel" I have to assume these people haven't looked at the performance characteristics or features at all. I didn't waste away weeks of my life. I needed something and couldn't find it anywhere. I'm outperforming many crap implementations by nearly an order of magnitude, and can offer queries upon the containers in both generalized and specialized forms. As an analogy, I made airless 3d printed wheels, and people are regularly telling me I should still be using ancient wooden spoke wheels; they probably would argue in favor of using a horse drawn carriage as well. How is it possible technically minded people can also be so anti-progress?
2) "Please rewrite this in X language." You know what? YOU rewrite it. I chose what I did because it made it easy to do what I needed to do. Hilariously, the languages I get asked to use most often, are the same who's containers libraries perform worst in the benchmarks.
Both sound like half baked developers trying to sound superior. Pull your head out of your ass and actually outperform me and others. I'm so fucking sick of this "all talk no action" bullshit.5 -

My boss's SQL schema has no foreign keys and he said he left them out intentionally because they should be handled in the application layer and they're a large performance impact.
This is a fresh greenfield project and he's already pre-optimizing for problems we don't have yet, on things that may or not be bottlenecks using ideas (e.g. foreign keys have huge performance costs on mariadb/auora) with no hard data or facts to back them up.

I am forced to work with a client's notoriously slow SOAP api. Slow in this case is 1.5-2s per request.
The api is structured rather... creatively... at the same time. So we have to bombard it with thousands of requests to build our data base with historical SOAP data. Also the data sometimes is a couple of hours late, giving a flat line (all values at 0) until retroactively fixing the output for the same requests.
So to fill one dev data base with a year's worth of historical data (nice to have when testing a dashboard application) we hammer the api with ~20k requests (~1 million if we want to be thorough).
Best thing about that: There is no staging/test api and the prod api seems not to handle lots of requests at the same time very well...
Latest thought: Maybe we could put a varnish cache in front of the SOAP for testing. Better have wrong data, than nothing at all and we don't kill the prod clients every time we ramp up a new instance.

Been struggling with a performance issue for weeks, been writing a search engine (or sorts) for internal company use only. Discovered the locations that are being indexed contain a directory used for back up purposes that contain archives of everything inside it.
Wrote a means to exclude these directories, performance improves up to 1600% (top end, sadly, not across the board) feel freaking awesome.

I'm currently at a company where we have "performance reviews" every 2 weeks, and based on the outcome we get a percentage which then is used to calculate a performance bonus.
This is simply my manager (also a developer) who has his Excel spreadsheet, looking at tasks I did over the course of the past 2 weeks and almost nitpicking to find some fault. There is no code review or software demo to see what's been done either... I was there for the first 3 months and I don't think anyone had even open my code!
And when confronted, I get told that "You should also somehow be financially liable for the goings-on in the business", along with a 2 hour meeting to support that.
This is NOT how you motivate developers!
Apologies for the long rant...

Ever find something that's just faster than something else, but when you try to break it down and analyze it, you can't find out why?
PyPy.
I decided I'd test it with a typical discord bot-style workload (decoding a JSON theoretically from an API, checking if it contains stuff, format and then returning it). It was... 1.73x the speed of python.
(Though, granted, this code is more network dependent than anything else.)
Mean +- std dev: [kitsu-python] 62.4 us +- 2.7 us -> [kitsu-pypy] 36.1 us +- 9.2 us: 1.73x faster (-42%)
Me: Whoa, how?!
So, I proceed to write microbenches for every step. Except the JSON decoding, (1.7x faster was at least twice as slow (in one case, one hundred times slower) when tested individually.
The combination of them was faster. Huh.
By this point, I was all "sign me up!", but... asyncpg (the only sane PostgreSQL driver for python IMO, using prepared statements by default and such) has some of it's functionality written in C, for performance reasons. Not Cython, actual C that links to CPython. That means no PyPy support.
Okay then.1 -

Is it possible to record the time a thread spends processing only it's code?
E.g. capture sys.ms in thread A -> A is sliced and thread B runs -> B is sliced -> A comes back and captures current sys.ms. The resulting delta of Anow - Ainit includes the time that B spent on the machine.
Is it possible to account for this and get just the time A spent processing?
