All vCMP guest configurations might see a 4-5% increase in CPU usage while running on VIPRION and iSeries platforms with the vCMP host upgraded to v16.1.x
Increase of CPU usage of about 4-5% on the vCMP guest. This is not expected to cause noticeable performance impacts unless the vCMP guest CPU is already close to 100% use, when it is possible there may be up to a 15% TPS decrease. If you are running vCMP on VIPRION and iSeries platforms, first evaluate your scenarios and capacity plan if you plan to upgrade the 'host' to 16.1.x. Note: There is no CPU usage increase when v16.1.x 'guest' instances are run on an earlier 'host' version. Guidance: In determining whether to upgrade the vCMP host to v16.1.x, carefully evaluate the performance and sizing requirements of your specific configuration.
