Hi all
Has anyone migrated to Oracle Sparc T5 and running in LDOM (Oracle VM for Sparc) and noticed any performance problems?
We have migrated a few database from Sun Sparc M9000 to the new T5's and the performance is worse, for example running 60000 times select 1 from dual using a for loop takes 3 to 5 seconds in T5 where as in M9000 it took 2.5 seconds, same test running in several Intel and IBM P6 and P7 all get better results (from 1.3 seconds to 2.7 seconds).
The test is a bit vague but look like it shows the performance difference
Thanks
