Sun Memory Upgrade problem

Hi,

After we upgraded memory on Sun 4500 to 10Gb Oracle performance became very bad.
It is almost 50% slower.
Any ideas?

Also when the sessions parameter becomes high like 4000, setting autotrace on in sqlplus becomes very very slow.
For example select * from dual takes like two minutes.
