We are running GitLab Ultimate in three different environments. Like 2000 users each and each user pipeline runs crazy like hundreds amounts of jobs. GitLab is keeping up. But we are sized for the 40 RPS architecture
Just in case anyone else (like me) didn't get the reference:
> This page describes the GitLab reference architecture designed to target a peak load of 40 requests per second (RPS), the typical peak load of up to 2,000 users, both manual and automated, based on real data.

Eventually, there was no virtual scaling that could help. This, for me, is the biggest problem with Gitlab hosting: as soon as you hit a scale where a single machine with Omnibus doesn't cut it, the jump in complexity, cost, and engineering hours is significant.
They have their free fast stats tool and you can run your logs through their tool to get statistics and identify hotspots
I would never use Gitlab for my own needs, but at company level, it's impressive how well it behaves!
