I've been using Cinelerra and others for doing DV under Linux and am looking
to optimize the performance a bit more. I was using Cinelerra's background
rendering facillity (just the one machine, I'm not doing any render
farming), and it got me to thinking about the frames it was writing to
/tmp.

Currently, /tmp is mounted as EXT3 (the journaling doesn't seem to decrease
performance much, if anything EXT3 seems a little quicker than EXT2).
However, it got me thinking that tmpfs and reiserfs might be better
performance replacements. I've got quite a bit of swap available (even more
if I commit the /tmp partition to it), so tmpfs might be a good fit. I've
found quite a bit of information on resierfs performance and figure it'd
offer a very modest improvement. However, I've found no information
characterizing the performance of tmpfs (I'm especially interested in it's
performance given an environment where there's a modest 512M of RAM and
gobs of disk space).

Anyone?
