i haven't played with interbase yet, but my understanding is they have
two types of server -- the "classic" (process per connection?) and a
"superserver" (multithreaded).  i'm guessing the multithreaded is faster
(why bother with the added complexity if it isn't?)  so which version
did you run this test against?

the other question i have is if it was possible that the disks were a
bottleneck in the test process.  it seems strange that three databases
would perform nearly identically for so long if there wasn't a
bottleneck somewhere.  were the drives striped?  did you consider
performing the test with faster raid arrays?  on a related note, i was
looking through a couple of back issues of db2 magazine, and it struck
me how much optimization and other performance hints there were
available there & how little there was for postgres.  is great bridge
planning on creating a knowledge base of these optimizations for the
public? or are you planning optimization as one of the commercial
services you provide? or some of both?
