I'm Yedil. I'm working on the project "Postgres Performance Farm" during Gsoc. Pgperffarm is a project like Postgres build farm but focuses on the performance of the database. Now it has 2 types of benchmarks, pgbench and tpc-h. The website is online here, and the repo is here.
I would like you to take a look at our website and, if possible, give some feedback on, for example, what other data should be collected or what other metrics could be used to compare performance.
