A few weeks back we ported our PHP Rest API into a couple of Go micro-services.

Incredibly _satisfying_ job.

Requests went from 20+ seconds to ~100-300ms.

There was still one bottle-neck, though, because we had to use most of the old cluster-fork of a database (because no way I'll be able to fix all that in a week).

And ooh, next we're thinking of switching to gRPC. Man, we have the best jobs.
