Tuning considerations
In version 3.x, high_performance profile is the default. Medium Granularity configuration can be changed to compact which would require less memory and CPU resources, however it may have some impact on the performance of the setup. With Fine Granularity configuration, including a mixed Fine and Medium Granularity, only high_performance profile is allowed.
The main difference between the high_performance (default) and compact profiles are the amount of server resources (CPU and memory) that are consumed. A high_performance profile (or configuration) will always consume more resources.
This document will describe commands using the PowerFlex command line interface (scli) to quickly and easily modify the desired performance profile.
Users will achieve optimum performance by always setting the performance profile to high_performance. A complete list of parameters comparing the Default and the high_performance profiles is available in the "Performance Parameters".
