Zeoslib Portal

Hi all,

It seems that the firebird3 driver in zeoslib is just a copy of firebird25 which means no real protocol updates?
The one that interests me is the new compression feature introduced in firebird3

Can you maybe point me to delphi firebird components supporting ver3 compression?

Hello duzenko,

Zeos 7.2-testing from the SVN should now support wire compression. Check out the latest 7.2-tesing SVN version and add wirecompression=true to the Zconnection properties. As I don't know of any simple way to check wether wire compression really happens I just implemeted it the way it is suggested in the FB 3.0RC2 release notes. Unfortunately firebird.conf and the release notes have different opinions on what the prequisites for successful compression are. It might be necessary for you to enable compression on the server side too.

With best regards,

Jan
