Of course, you may just have too many transactions at which point your hard-
ware can't keep up. But by monitoring the various hardware, operating system,
and infrastructure metrics, over time you should be able to determine whether
you have maxed out your current hardware capacity or not.
Is your environment always slow? Or does it demonstrate poor performance un-
der heavy loads only? Monitoring the performance of your environment is not
a one-time activity. You should have monitoring tools in place to help you pin-
point unusual or high utilization, and compare them to average usage times. In

(and even some administration) capabilities for both your SOA Infrastructure and
operating system.
By adding the SOA Management Pack, you would also be able to get composite
specific information of all your environments through a single console. Otherwise

Composite instance performance
When we refer to the inadequate composite instance performance, we mean to
say that a particular composite is behaving poorly. In these cases, performance
issues are often isolated to one (or a few) composites, but not all. For example,
this could be due to the response times from external systems, a badly designed
process, or due to a suddenly poor performing database or queue that the SOA
composite is using to read or write data to.
