Pavel Yaskevich updated CASSANDRA-1453:
---------------------------------------
Attachment: stress-v2.patch
.gitignore and @author tags removed. -server and -XX:CompileThreshold=1 added
to ./bin/stress
I can add --warm-up option to the system which will run required action
(insert, read etc.) with given by user parameters before measuring performance
and then run actual tests, this is only way to perform warm-up I see here. Any
other ideas?

> 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.
