Performance question/insights

[bikashmishra]

A question rather than an issue.

We’re hitting a bottle neck and mosql is not keeping up with the oplog. We’re generating about <1000 write ops per minute and all the systems are running on top of AWS (mongoDB, mosql, postgresql on RDS). It’s not clear what the bottleneck is since the CPU and RAM doesn’t seem to be a problem (on any of the instances) and we are using 2000 provisioned IOPS on the RDS and Mongodb sides. Any clues? Is there something in the mosql processing that we could optimize?

Thanks!
