Franz, I have a couple of questions. What release is SQL/DS? Is the SQL/DS server using VM dataspaces? Was their expanded storage on the old box? If so, how much? Is the Tserver configured with expanded storage? If so, how much? Did the old system have cached DASD? Are you using enough cache for the DASD on the Tserver? Are you paging on Unix/Linux at all on the Tserver? Ed Zell (309) 674-8255 x-107 [EMAIL PROTECTED] .
