I agree, excellent work Scott!

I think one of the interesting questions now is (and you've mentioned
this yourself in the document) how different filesystems would affect
the PStore performance.

While I'm not looking to start a platform war here or really have any
figures to back it up with, NetBSD is probably not the most widespread
os for typical Rails applications.
So I think it would be interesting to see some pretty graphs from
different filesystems, like UFS (?) on FreeBSD, ReiserFS/ext3(/xfs) on
Linux and HFS+ on OSX, if only to have some more data to look at.
(Of course, if I get around to do this myself, I'll send any findings
to the list, but I'm a little low on time right now..)

Maybe I'm misstaken here, but I also seem to remember something about
how writing works differently in InnoDB vs. MyISAM in MySQL table
types, I seem to remember one of them was locking the entire table (or
db) when writing to a table and the other didn't? But of course I
can't really remember any more details than that. And according to
these graphs anyway the tabletype in mysql won't really affect the
session performance..

Again, great job Scott, thanks for sharing!
