Hi Roman,

Good. I'm glad that I've been able to stick your attention to this problem.
I really wish JB to fight it and be on the top again.

No Roman, it isn't 'specific to local connections only'. Here it is the
results
on remote connections:
args[0] = linux
args[1] = fb
org.firebirdsql.jdbc.FBDriver
jdbc:firebirdsql:111.111.111.111/3050:/home/volin/test.gdb
time1 = 441 time2 = 90 time3 = 59646
time1 = 561 time2 = 60 time3 = 66175
time1 = 601 time2 = 190 time3 = 135155
My best network transfer speed is about 200Kb/s on ftp. This is complient
to the results.
Unfortunately, I can't reproduce tests with IC now - it gives
API.BadInstallationException to me
what I can hardly correctly interprete cause IC works locally well and 3060
port
on which interserver works is open to my pc. Is it one of the most IC bugs
then?
By the way the version of IC I use is sooner 2.01 then 2.5 - I was confused
by
information shown by CommDiag applet. IC is really confused. But still works
though.

Thanks, Sergei Volin.
