> After functional tests, we are performing load tests against James Server
> setup with Casandra/Elasticsearch packaging option. With JMeter constant
> throughput timer of 300 SMPT requests per seconds we are achieving around 10
> requests per seconds. Each Request is with 100KB attachment. Observed CPU of
> the machine (where MailServer running) was over exhausted.
> Many of the threads in thread dump were in awaiting notifications state.
> I see around 100 threads from Elastic search, is there any configuration to
> control this?
> Where is the bottleneck?
