**As a** performance engineer **I want to** capture performance baseline of the metrics specified in https://gitlab.com/gitlab-org/gitlab-ce/issues/61291 and configurations specified in https://gitlab.com/gitlab-org/gitlab-ce/issues/62876 after switching to Puma server **So that** I can produce a side-by-side performance comparison between Unicorn baseline (https://gitlab.com/gitlab-org/gitlab-ce/issues/62877) and Puma web servers. **Acceptance criteria**: Side-by-side tables of **each** configuration like below | | Unicorn | Puma | | ------ | ------ | ------ | | Metric 1 | | | | Metric 2 | | | | Metric ... | | |
