I'm using Firebird 2.0.3.12981 on Suse Linux 9.0, and the IBPhoenix ODBC
driver 2.0.0 on Windows clients. I've been using Wireshark to monitor
network traffic to look for inefficiencies. A particular series of
transactions generates over 11,000 packets and over 6.5 megabytes of
data. The same series of transactions using MySQL generates just 725
packets and 121 kilobytes of network traffic, and goes significantly
faster. Much of the 6.5Mb of data sent using Firebird turned out to be
long streams of zeros. Wireshark labels these packets as Protocol "IB"
(ie Interbase), Info "Reply void". Can anyone tell me please what's
happening here? How do I stop this behaviour?

Regards,

Robert.
