On my opinion CompileThreshold set to 1 is a good option for stress to warm-up as wanted but the price of it is slow start-up time, you can remove that if you want. > stress.java > ----------- > > Key: CASSANDRA-1453 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1453 > Project: Cassandra > Issue Type: New Feature > Components: Tools > Reporter: Jonathan Ellis > Assignee: Pavel Yaskevich > Priority: Minor > Fix For: 0.7.1 > > Attachments: stress-v2.patch, stress.patch > > > stress.py seems to scale poorly past a fairly small number of threads/processes. (against a 3-node, RF=1 cluster, I got 3x as much throughput with 4 machines running stress.py -t 32, as running 1 with -t 128. these were 8-core client machines, and -t 128 reported only 50% cpu used.) > since we ship with the thrift java api pre-built, this would also mean not making people build thrift before using the stress test, which is at best a pain for newcomers and on Windows a major hurdle. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
