RE: iReach bad performance

Post the onconfig file and the hardware on the Sun Server. I hope you did more to tune the instance then increase the number of buffers ;). Wayne E.

Hi Martin and thanks for your email. Yes I tryed to increase the number of buffers from 20480 to 100000, but it did not change the responce time. The machine is a SUN Enterprice 3500 with 4 CPU's and 2.5Gb memory. The disks are A5000 boxes with dual optical interfaces. The disks are striped and mirrored.
