We've added some Sun T2000 series servers to our data center and they
are much slower all the way around. We've done benchmark tests on them
to prove it. Basically, you get what you pay for. They are cheaper
than other Sun servers. According to one of our SAs, the reason that
they are so much slower is that they don't do hardware floating point
calculations, it's all software. I've even noticed a 3x to 4x slower
transfer rate between servers when using scp if even one of the two
servers is a T2000 series. We try to put test databases on them and
leave production on the other servers.

Subject: Oracle on Sun T2 performance problems
We are having performance problems with Sun T2 platform, especially with
RMAN backups. The database consists of about 75% blobs.
Has anybody run into major performance problems with RMAN either on a
Sun T2 or on a 10g db with lots of blobs ? Our disk I/O has far more
i/o capacity than is being used.
