Performance Considerations
These items warrant consideration since they have potential for a
negative impact to performance.
Performance APARs
Large VM Systems
Performance APARs
There are a number of z/VM 5.3 APARs that correct problems
with performance or performance management data.
Review these
to see if any apply to your system environment.
This was first listed as a consideration
for z/VM 5.2 and is repeated here. Because of the CP storage
management improvements in z/VM 5.2 and z/VM 5.3, it becomes
practical to configure VM systems that use large amounts of real
storage. When that is done, however, we recommend a gradual, staged
approach with careful monitoring of system performance to guard against
the possibility of the system encountering other limiting factors.
With the exception of the potential PGMBK constraint, all of the
specific considerations listed for z/VM
5.2 continue to apply.
