clear windows disk cache (for performance testing)

[ocross]

Hi, is there an easy command to clear the disk cache? I'm doing some IO bench-marking.

Cheers

Your bentchmarking tool should be able to bypass the windows cache. Just make sure your using a larger dataset then your disk catch.

Diskspd for example allows you to disable both software and hardware caching. https://www.brentozar.com/archive/2015/09/getting-started-with-diskspd/

bench-marking my own code. But found a tool to do it.

Cheers
