Tom and Clay,

Not only is it NOT necessary to execute the schmon commands for components that have not changed in your priority scheduler scenario when you move from one performance window to another, but for performance reasons, you probably want to avoid doing that.

That is because the internal UNIX file structures that hold this information on each node get re-written in their entirety ONCE for each schmon command issued, whether that particular component has changed or not.

There may be times in the development cycle, when you've been doing a lot of trial and error-ing with your settings, where a complete refresh is a good idea. But I'd avoid the complete refresh as a regular everyday thing.

Thanks, --Carrie
