[mythtv-users] Which filesystem deletes large files the faste st?

I have a separate mountpoint on an internal drive 20gig in size for the
ringbuffers. After about 24 hours this 20gig mountpoint will nearly fill.
With reiser when I escape from LiveTV this nearly 20gig file would take 30
seconds or more to delete. After reading this list I switched to JFS for
this mountpoint and just tonight tested it. A 20gig file under JFS deleted
in less than a second. I think hands down JFS is best for the ringbuffer.

you are looking at.  I am using XFS, and find that deletes take almost no
time at all with 2-3 Gb files.

I used to use ReiserFS.  It was great for most things, but deleting files
was particularly slow.  I switched to JFS (after reading the mythtv
documentation - hint, hint) and it is much, much faster at deleting.
