may want to modify the workload characteristics. You would do this to increase system
load in order to find the maximum system performance or headroom that can be
expected of the system once it is virtualized. This is very important during validation of
your virtual infrastructure and virtual machine design prior to migrating your production
systems. A relatively small amount of effort now can return you greater performance and
stability later when your business and your workloads change.
Figure 10.2
shows the
strategy of baselining and benchmarking to ensure valid performance comparisons.

Why Should You Take a Performance Baseline?
Your performance baseline will be used to validate that the virtual infrastructure and the
design of the virtual machines meet or exceed the requirements of the source physical
systems, both before and after they are virtualized.
The following are the most important reasons for taking a performance baseline of your
source and destination systems:
Reduced risk of not meeting requirements
Increased ROI by being able to optimize infrastructure utilization
Reduced risk of over- or under-investment
Prevention of performance problems during database and infrastructure
configuration changes
Significantly easier, more accurate, and quicker architecture design process
