Hello, I've already asked this on the FireBird forum and got no replies:

I'm using IBO and Firebird (2.1), embedded, in a desktop application.

Recently, a user started really complaining that his program was very
slow (about 10x slower than other users). After coaxing him to try
running the program in Safemode in Vista, he noticed a MUCH better
response (i.e. in the ballpark of other users). He then methodically
looked at all his startup programs and processes and found a BlueTooth
program to be the culprit. He eliminated loading that, rebooted but then
found that there are other programs that are still slowing FB WAY down
(a recent grid which takes about 5 second to load, took him a minute to
load). He stopped looking but did not stop complaining about his "slow
program." : )

Is there anyone who can help me to know what type of programs my users
should not be running with the DB intensive program that I distribute?
Are there specific issues here? Any general recommendations that I can
make to my users?

Admittedly this user is one of those types that load up about 20 (and
I'm not exaggerating!) programs and expect them all to run just fine. He
does have plenty of RAM (I think he said 6Gb). He's running 32 bit Vista
on a laptop. Our support person does say that out of about 100 users
there are 2 others with similar problems, but they do not run a lot of
programs in the background.

Thank you for any help.

Chuck Belanger.
