My understanding -- based purely on hearsay and folklore -- is that in
modern Unices, inet-domain sockets to 127.0.0.1 are just as fast as
Unix-domain sockets.  I've never bothered with benchmarking it though --
if you're really concerned about it, you should do some timing tests!

Also, keep in mind that ZODB is designed for frequent reads and
infrequent writes.  You might be hitting fundamental design issues, or
you might just be hitting inefficient code that no one has bothered to
optimize.  Try profiling: hotshot works pretty well if you can dig up
Fred's presentation from IPC10 (the only docs AFAIK).
