Very Slow Performances ?

I noticed this in several different configurations : Example : 12 schemas 1 schema has 4000 records to replicate by a xDSL line -> 130rec/minute 1 schema has 150000 records to replicate by a xDSL line -> 32rec/minute if I put on the same server the 2 databases (so, no xDSL line, just 127.0.0.1), the speed for 150000 records is 40rec/min... If a lot of lines are in repl$log table for one schema, the replication (online) is slow. I made A LOT of tests with different PCs, different lines, different databases, I always noticed that... I also tried to put 2 databases on the same server as the replication server and it's also very slow... Version of IBReplServer : 2.0 (12.1) Is there something wrong ??? How the "SELECT FROM REPL$LOG" is done within IBREPLSRV ? In version 1.0, it was a "SELECT * FROM..." (without a where)... But I don't have sources for version 2... If needed, I can provider full ReplicationDB, and 2 production DBs to simulate this problem. Upgraded to 2.0.15.1, same problem... Also, I do not have the glyphs on the buttons.... Please, help ....
