Set up perf test pipeline and monitoring

- [x] Work was started for perf tests such that we have them and can run them, but right now it's a manual effort and not something that we actively run or monitor. We should set it up so it runs on a set schedule and keep an eye out for issues coming from it.
- [ ] Set up monitoring/compare perf numbers to a baseline
