Aleksey Yeschenko resolved CASSANDRA-10712.
-------------------------------------------
Resolution: Duplicate
Reproduced In: 3.0.0, 2.1.11, 2.0.17 (was: 2.0.17, 2.1.11, 3.0.0)
> Performance dramatically impacted by using client SSL
> -----------------------------------------------------
>
> Key: CASSANDRA-10712
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10712
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Andy Tolbert
> Attachments: bench-graph.png, cpu_metrics.png, ssl-bench.tgz
>
>
> Throughput latency & throughput achieved via cassandra-stress is dramatically
> impacted when using SSL (about 5-6x).
> !bench-graph.png!
> I haven't done much analysis of this yet, but one observation is that I do
> notice a dramatic increase in context switches while running with SSL on the
> server side. In the charts below, the left-most data in a chart represents
> running without SSL, and the right-most data represents running with SSL.
> You'll observe that on the C* node that while the CPU utilization is down
> when running stress with SSL, the context switches are higher.
> !cpu_metrics.png!
> Attached is [^ssl-bench.tgz] that includes output for each run, the
> parameters used and an html file that is the output of running stress with
> [CASSANDRA-7918].
> If you need some ready made keystore / truststore files to work with, some
> can be found
