Need guide on how to identify bottlenecks
Opened this issue · 0 comments
From several discussions in slack, identifying the source of a bottleneck when running Open Match is not trivial. We should write a guide on finding and resolving bottlenecks within the system, including any of the services not receiving enough resources:
- Frontend
- Backend
- Synchronizer
- Redis
- Evaluator
- MMF
Additionally, the guide should go into how to use tracing to see how long various operation are taking.
I think it may be worth building a tool which can download all of the currently searching tickets via query API, and then re-create them in another system. This would allow for testing various configurations without having to using a live production service. It could also download the tickets over time, so you can generate an artificially large number of tickets based on real data.
