The following are tuning considerations for VVR compression:
VVR compression results in additional CPU utilization on the Primary and Secondary hosts when enabled. It is recommended that you provision for this CPU overhead by allocating a dedicated CPU.
Reducing the number of compression and decompression threads on the Primary and Secondary hosts reduces the amount of CPU consumption.
In cases where CPU utilization is very high, it is recommended that you either disable compression or reduce the number of compression and decompression threads that are set on the Primary and Secondary hosts.
