Related, I've been considering filesystem based filters on SSD. That
ought to be rather fast, consume no memory and be as simple as a
RandomAccessFile. I didn't spend to much time on it, gave up when I
couldn't figure out when it made sense to close the file. Perhaps it
would be nice with a close method in DocSetIterator.

I'd be curious how much of a performance difference you see between
the different SSD drives.
This test was with OCZ "Core Series" but previous tests were with
different SSDs right?
EG Intel just released a new 80 GB SSD (X25-M) which is getting rave
reviews, even compared to the OCZ "core series" which seemed to be
the previous favorite:

Hi all,
We stuck a 60 GB OCZ "Core Series" SSD in a Dell T5400 (dual
quadcore, 16GB RAM, SATA II 7200 RPM disk) and did some comparisons
between running with our index on disk, vs. on SSD. I can't really
talk about what the app does, but I can share the difference in
performance; see enclosed PDF.
We have a 15GB index and a 20GB bdb, both of which are on the SSD.
Pretty amazing performance difference. "Go buy one now." :)
(The x-axis is ms/request, the y-axis is percentile. So, "65% of
SSD requests took 120ms or less", for example).
cheers,
Eric
