Hi!

Are there some known issues between Firebird 2.5 (SuperServer, default 
install) and Windows Firewall (from WinXP)? Today is the second time I 
encountered some serious slowdowns while the XP's firewall was running 
which went away when I disabled the firewall - a simple query, which on 
another computer (or the same computer, but with a different version of 
Firebird) would take 0.1 seconds, would run for 15 to 18 seconds with 
the firewall enabled, *but only in some applications* (e.g., if I 
executed the same query from IBOConsole, it would run in the expected 
time). I am particularly baffled by two things:

1) That the communication doesn't get blocked completely but instead 
just slowed down by two or three orders of magnitude.

2) That this slowdown would appear in some client applications but not 
in others, despite the fact that all of them connect through TCP/IP.

If it happened once, I would brush it off as a random craziness of 
Windows, but the second time has me worried. Especially since the second 
case appeared suddenly, without any obvious reason and after running for 
quite some time without any issues. Any ideas?

Josef
