BIG Istar performance problem

Subject: BIG Istar performance problem. ---------------------------------------- I have a very big performance problem with Istar. My server is an Data General AViiON 9500 (2 cpu's) with 4 OnLines. I have 2 Data General clients and 2 Pyramid MIServer clients. There is also activity between the OnLines on the server (Istar by usings "local host". A simple testprogram have been created to measure times for open database, select etc. On the server I have 300 to 500 sqlturbo processes. No frontends runs on the server. All frontends are version 4.10.xx and all backends are version 5.00.xx. If I run my test program on the server, when the load is high without using Istar, the total used time is very low, it may be 0.07 sec. up to 1.00 sec. If I run my test program using Istar from the server or from one of the clients the used time gets very bad, the time peaks up to 190 sec. Actually it is not useful to run client server for the normal users ! Do you have any input that might help me ? If yes please write a mail.
