Before going the distributed DB route, have you tried making your CGIs
resident? With some concepts, like FastCGI, each resident process can
have an open connection to the DB - therefore dramatically reducing O/H.
Also with FastCGI you can have multiple copies of your heaviest used or
time consuming CGIs resident. The first free one gets the request.
Unless you are disk bound I'd suggest looking into adding memory and
resident processes.
