Just curious, has the topic of using shared memory been brought up?  I've
used shmop functionality to store large data trees which were imported
from XML.  Parsing the XML doc would take 500-800ms, but unserializing a
large object from shared mem took like 6-7ms. This was for a drupal 4.2
module, but I would imagine the code could easily be adapted.
I realize that shmop is not available on all platforms, but probably most
server-grade environments would/should support it.
