Performance problem Linux vs. Solaris

Hi,

I have a problem with Oracle 8.1.7. I installed it on a 2 processors Intel linux machine. The database I use is not at all optimized, means I did not spread any datafiles across disks and I have only one tablespace.

The application working on that database produces around 2500 transactions per minute on that machine. When I install the same database on a sunfire V280, the transaction rate goes down to 400 transactions per minute. The sunfire also has two processors, and a lot more real memory (4 Gigabytes). When I look at the cache hit ratios, there's no hint of contention, all ratios are above 90%. In addition, there apear no wait events in the system.

I think that there is perhaps a problem with Solaris 2.7 and Oracle that I don't know. Does anybody know about a certain parameter to adjust in Oracle or Solaris, or can anybody give m an idea of what I can exmaine to solve the problem?

Thank you for every hint
