This may be due to multiple processors, a problem Microsoft introduced
in their TCP/IP stack in XP and Win2k or a combination of the two.
There is a freeware program called IBAffinity that you can use to pin
IB to a single processor. That will solve the problem of Windows
constantly swapping IB from one processor to another to try to balance
the load.

Not in the open source version of InterBase. Borland abandoned the open
source version years ago and returned to developing InterBase as a
commercial product. The current version is InterBase 2007 (8.0) which
supports hyperthreading, multiple processors, the TCP/IP problem
mentioned above and includes a host of new features added in versions
6.5, 7, 7.5 and 2007.
