URGENT: Slow Performance after migration to 9.2.0.3 from 8.1.7

Dear all,

We are having significant performance degradation (10 to 100 times) in the execution of the queries on the Oracle 9i server, after migrating the database from 8i to 9i. 9i has been installed on a new machine
(not an upgrade, 9.2 & Patch Set 2), database dump loaded, statistics
computed anew... The servers are Windows 2000 & Solaris, drop in performance is experienced on both 9i environments....

Server info:
9i: Windows 2000 SP 4, 4x700MHz CPU, 2Gb RAM, 2 disk arrays 0+1 - All objects (tables & indexes in one tablespace on disk array 1) redo logs on disk array 2. Sorry, this could not be changed for now -- version control....

8i: Windows 2000 SP 2 2x600 MHz CPU 1Gb RAM - no disk array, all objects & redo logs on the same drive.

9i: Solaris - 5.8 Generic_108528-14 sun4u sparc SUNW,Sun-Fire-280R, 2x700Mz CPU, 2 Gb RAM Sun disk array.
The results were the same as the Windows 2000 9i - 10+ times slower than 8i.

Shown below (pardon the length) is the statspack report on the new box... Is there anything that raises an eyebrow?

Thank you in advance!

Shared Pool Advisory for DB: EUROPA Instance: europa End Snap: 6 -> Note there is often a 1:Many correlation between a single logical object

   in the Library Cache, and the physical number of memory objects associated

   with it. Therefore comparing the number of Lib Cache objects (e.g. in

   v$librarycache), with the number of Lib Cache Memory Objects is invalid
