NT -> Win2K causes performance degradation..

Hi All,

We've been asked a question from one of our clients that I'm a little stumped on.

They run an OLTP database (Oracle 8.1.7), and have recently upgraded their NT machine to Windows 2000, they were running with 2gb of memory, and upgraded that to 4gb in the process. As they increased physical memory, they also increased their SGA size & db_block_buffers.

Since they've upgraded they have noticed a significant decrease in performance (the way it was described to me was "it was 7 out of 10, and is now 3 out of 10"..).

Has anybody else done a system upgrade of this nature that has caused less than desirable effects? Any pointers as to what to look at? We've requested some stats (top wait stats etc.) and I'll feed these back as and when I get them - but I thought I'd throw this out to you guys in the vague hope that someone has experienced some relatively similar experiences.

Cheers!

Mark
