I did many of the tests that you mention above. I finally got to the
point were I bought half a gig of ram (now have approx. 800Megs) and
mounted my "Record Directory" on a tmpfs. I move everything in tmpsf and
only do periodic saves to hard disk of the files that are changed as I go.
I guess the (overly obvious) quesion is, are you running as root? It
sounds like you're savy enough to have thought of that. But I just
thought I would ask (just in case). Running as root can eleviate certain
problems.
