Subject: how to empty buffers/cache?
Date: Fri, 09 May 2008 21:49:47 +0000	[thread overview]
Message-ID: <1210369787.4142.24.camel@localhost> (raw)

Dear all,

I am trying to perform some benchmarks that involve reading the same big
file a couple of times from disk. However I would want to make sure that
the file is not buffered/cached by the kernel when I read the file a
second/third/etc time.

Is there a way (except rebooting/unmounting the disk) to clear the
buffers?

Thanks,
Soeren
