We hear you and agree, GitLab.com is too slow. We're working on multiple things to improve it https://gitlab.com/gitlab-com/infrastructure/issues/947 GitLab 9.1 will have lots of performance improvements for database queries. The GItaly team is working hard to move git commands to the fileservers to reduce latency, that will happen in about a month from now.

Idea: put the performance plots from tickets on https://arewefastyet.gitlab.com

Mozilla does this to great effect:

Great idea! We've just forwarded http://arewefastyet.gitlab.com/ to http://monitor.gitlab.net/dashboard/db/fleet-overview

This doesn't show all the graphs we need to show like 99th percentile request latency but that will come when we add Unicorn support to Prometheus.

This is the reason we love you guys, clear communication and caring for what people have to say. Keep doing that and we'll keep loving you. :D

As a thought for the performance diagnosis part of things, if your network switches have the option to enable NetFlow (also known as IPFIX), it can be extremely useful.

It does need to be paired with something that can capture and display the NetFlow data well. But with that, you can literally see what data is going where in your network, accurate to the byte. And with a good visualisation solution, you have the data historically too, so you can (easily) match things up time wise.

eg a developer writes a bad query which pulls 1/2 the database over the network to the front end server for filtering results there, instead of filtering them in the database. You can see that on the network fairly easily, and let the developer self-educate (if given access to the tools). ;)

As an aside, the gold standard used to be a commercial product called "NetFlow Tracker". It was amazing (fond memories), but the company behind it (Fluke Networks) didn't seem to know anything about software sales. So, it's now discontinued. :(

Hopefully there's a modern version of that somewhere. :)
