Thanks for the feedback. We are working hard to improve performance and memory consumption of GitLab. We have two major projects underway, switching to Puma [1] as well as reducing the overall memory consumption of GitLab [2].

You can follow along on some of the progress we are making in each release post in the "Performance Improvements" section. For 12.2 you can see we had 58 MR's related to performance.
