[mdlug] OT: Solaris 10 Priority Scheduling

[David Lane]

Hi, 


We are facing a challenging issue.

We have performance issueson a multi CPU server. Our benchmark (sum of square-roots 1 - 1,000,000) runs 20 sec on a a multi cpu system. Yet it runs less than a sec on a single CPU system and on my desktop. 

When we found this we started to explore scheduling priorities.

If a process is running slow and needs to run faster on Solaris, what are odd options to tweek performance?
 
Where are SYS 60-99 processes assigned ?
