[mythtv-users] Raid Performance Tweaking

[Dean Wilson]

I know that many of us are interested in Raid, but don't really know
the best configuration for a myth setup.  I, like many others here, am
interested in Raid5, and would like it to perform optimally for (very)
large files.

I've read http://www.tldp.org/HOWTO/Software-RAID-HOWTO-9.html, which
gets into chunk and block size performance testing, but doesn't use
chunks above 32K.  I would think that a larger chunk size would be
ideal for myth, as it uses exceedingly large files.

I figured I'd use bonnie to measure performance gains/losses, since
that's what the howto used.  Obviously I'll play with different
chunk/block size combinations, and will report my findings.  But I'm
curious to know if anyone out there would be interested in any other
specific tests?  If so, let me know -- I'll try to include them, and
will put together a web page with the results I find.

Thanks,
~Dean
