These tests examined the pub-sub performance of the Redis driver (Juno release).
In these tests, various amounts of load was applied to the following configuration:
- 1x4 load balancer
- 1x20 web head (WSGI server)
- 1x1 redis (message store)
- 3x mongo replica set (pooling catalog)
In these tests, observers was held at 50 while the number of producer clients was steadily increased (X axis). This simulates a write-heavy workload.
The Y-axis denotes mean latency in milliseconds.
