Server downgrade with Identical storage could cause performance degrade too.
I have seen case, when we upgrade from 880 2900, storage not changing, and
a simple full table scan time reduced to half. It could due to just server
bus faster, CPU speed is same for 880 and 2900 I think, 2900 was dual core,
but my full scan job is not using parallel at all.
You are doing the downgrade actually.

We have just gone from a Sun 6900 to a Sun 1280, from 8 CPU's to 4 CPU's
with 1.5 (versus 1) Ghz processing power . They are called Ultrasparcs.
We are running both Oracle 8.1.7 and Oracle 10. Performance has degraded
and it looks to me that the bottlenecks are I/O. However, I am hearing a
rumour that Oracle 8.1.7 does not take advantage of the Ultrasparcs.
Has anyone dealt with this issue and where is it documented?
Thanks,
