Hello,

We are a SAP shop and do not run WebSphere.  However we do run some SAP
Java instances.  On some of those systems, we have found it beneficial
to define two CPUS, and let the garbage collector know about it.
Depending on the size of your heap, sometimes the the garbage collection
times improve noticeably.

Can some of you weigh in on the merits (demerits) of defining multiple CPU's
to virtual Linux boxes?  We are heavy WebSphere and have gotten differing
opinions.
The typical advice is that if you are driving a single CPU over 80%, then a 
second one would likely be useful.  Otherwise, you just add to z/VM's workload 
to schedule that virtual CPU with no benefit to the guest.
