It's probably the known logging bug in 0.60. This caused a very large
slowdown on many systems. Upgrade to a recent FreeTDS snapshot or wait for
the next release, and it should be much faster.

You might want to run ethereal on that box and see if the delay is between
request and return or the other 'way round. That will at least tell you
which machine to start looking on. Then look for ways to time the components
on that box, to find out which is the culprit.
