Unrelated to that incident, but I feel their web UI to be extremely slow lately. Working with PRs (or "merge requests" as GitLab calls them) and CI pipeline is a pain, you're looking at 1 second response times.
We're not happy with the merge request speed either. We're close to converting the merge request view to Vue, this should speed it up considerably.
To me it doesn't look like it's a front-end issue. I am mainly complaining about the HTTP response time. It seems extremely slow on both pipelines and merge requests, and Vue ain't gonna fix that I'm afraid.
I don't know if it's an optimisation issue with the software itself, or if it's just GitLab.com being overloaded..
Because we're loading everything in one go the database query time and rails rendering time adds up.
