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 > [here|https://github.com/datastax/java-driver/tree/2.1/driver-core/src/test/resources]. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
