Cachebench config to specify time

[wangyuyue]

Hi developers,
I want to test the cachelib performance for SSDPerf benchmarks provided in the repo. Instead of specifying a number of operations per thread, I want to specify a time duration. Is there any built-in configuration option for that?

Thanks,
Yuyue

Hi @wangyuyue,

For the purpose you mentioned, cachebench provides the command line option -timeout_seconds; see cachebench --help for details. Please note that the test would stop once whichever shorter one among numOps and timeout is reached.

Thanks.
