Hi,

I want to benchmark my pair of fancy new 250GB disks in RAID 0 mode to find out the best cluster sizes for:

compiling (or 'emerging' as some may call it :-)
loading large levels in games (i.e. quake 4)

How can I clear Linux's memory-cache-of-recently-used-files-dunno-what-its-called so they do not interfere between runs of the benchmark? I know a reboot would work, and that's what I did under Windoze. But this is Linux!

Thanks

Thanks.

You can delete this post if you want, since its redundant.

I honestly spend 30 minutes searching all sorts of places looking for this answer, using terms like 'clear disk cache linux' and 'linux benchmark raid clear cache' and all sorts of stuff, so please don't think I just posted without doing some work first.

Many thanks for the answer.

Moved from Kernel & Hardware to Duplicate Threads in favour of the above mentioned thread.
