Josh looked at logs from instances and noticed that Nairobi only processed ~1k documents when it should have done 10x to 100x more. Why is it moving so slow? CPU!!
-
When there’s spare CPU we see a more normal sentinel processing speed
-
Why does a spike in network traffic correlate to a drop in CPU use? We would expect the opposite?!
-
Does purging have an effect? A bit of research was done, but it’s otherwise running every 24 hours.
-
Run test to see if we can narrow down CPU use source
- 30 min total
- 15 min stop HAProxy
- 15 Min keep HAProxy stopped, restart Couch
