Hi,

i did performance measurements with different SGA sizes on different CPUs.

IBM RS6000 5xx and SMP, SGI, HP. Oracle 7.x

I found that a small SGA performs better than a big SGA !! I believe this is because filesystem caching performs better than Oracle SGA-caching.

Give a small SGA a try!
Make Oracle-blocksize as big as possible.

Kind regards,

Toni
