RE: Linux buffer cache monitoring

Hi Henry,

I've never used Direct I/O on Linux, but I'll look into it. I don't see any options with the Orion utility to force it to use direct I/O, but maybe there is a filesystem mount option I can use to force it similar to the cio mount option on AIX.

I considered using raw devices to test too, but my sysadmin is telling me that is difficult/impossible to setup because this is actually a virtual environment, running on top of Win2K8 HyperV, which is one reason why I want to make sure we're getting sufficient IO throughput.

Thanks,
Brandon

I forget if it can be used with
Direct I/O.
