My company runs TSM 5.1.8.1 on Sun E4500's with 4 procs and 4GB of RAM. 
 I have tried twice now, once on 4.2 and now on 5.1 to add more processors 
(either 2 or 4) and TSM performance drops through the floor.  Has anyone else 
seen this behavior?  Normally, starting the server fresh only takes 10-15 
minutes to mount all of the volumes and bring everything online, but with the 
additional processors, it takes hours.  I have tried it on several machines 
with different code levels with the same effect.  I have also tried it on both 
Solaris 2.6 and 8, same effect.  Any suggestions from the peanut gallery?
