Hi ! I have a strange slow performance problem depending on client computer. I have a postgresql server (8.1.3) running on an XP system (P4 3GHz, 1Go RAM). I have 3 other computers from which I make request on the database : 2 XP(named 1 & 2) and 1 2K. >From one XP(1) and from the 2K computer, I have no slow performance problem. I ask for a select of 4000 records, the request is processed in less than 1 seconde. >From the last XP (2) computer, the same request takes more than 10 seconds. From this computer I have no other network problem, I can copy, paste network files without any performance problem. The 3 clients use odbc driver 8.01.02.00. I tried to install the postgre sql server on the xp (2) and make the same request from 3 other computers : no problem, the process takes less than 1 second from all clients what goes wrong ?? thanks for your help Mike
