Hmm, it would seem not... the cat happens instantly:
(env)tsa@sp2772c:~/sports$ time cat Data_IndexDB.fs > /dev/null
real 0m0.065s
user 0m0.000s
sys 0m0.064s
The database isn't even very big:
rw-r--r-- 1 tsa tsa 233M Jan 18 14:34 Data_IndexDB.fs
Which makes me wonder why it takes so long to load it into memory.... it's
just a bit frustrating that the server has 7gb of RAM and it's proving to
be so difficult to get ZODB to keep ~300 megs of it up in there. Or,
indeed, if linux already has the whole .fs file in a memory cache, where
are these delays coming from? There's something I don't quite understand
about this whole situation...
