    @galileopy what do you use then? How do you find memory leaks in your lang.? Don't your lang heap [core] dump analyzers consume loads of memory? :)

    Well think about me ;_; i use only 8gb memory to do this with a 940mx 2gig graphics ;_;

    @spantheslayer to do what? Analyze 10GB heap dumps? I don't think gpu is useful for that.,

    @netikras not that much ;_; I only used around 3/4gb of dump logs ;_;
    Still it takes much time to find leaks ;_;

    @spantheslayer yepp it does :) that's why I tried heaphero. It works quite well but it needs shitload of memory to process a dump. In this case for a 10G dump it needed 24G or so ram.

    It's great that I am running linux tho - I can throw in some swap any time to extend my ram :)

    what do you use for dump analysis?

    Android building. Eats 24G ram in one go. Then Java starts oh boy.

    @spantheslayer well its nightmare for me with 16 GB Ram and 16gb swap. Will update to 32gb ram if I have the money.
