Its quite easy to get bad performance, if people install all things as "standard" or you have a poorly written application.... Currently, we have a 58H with AIX 3.2.5, ORACLE 7.0.16, 6 GB database, 256 MB RAM, 70 concurrent users, several modems handling over 20000 order-positions in 6 hours. All orders are processed and shipped the same day (in these 6 hours). > Willy Klotz > ====================================================================== Willys Mail FidoNet 2:2474/117 2:2474/118 willyk@kbigate.stgt.sub.org VFC ISDN/X.75 -> No Request from 06.00 to 08.00 <- ======================================================================
