How to set up each performance parameter?

There are lots of ScaleIO performance parameters as written in CHAPTER 5 of EMC ScaleIO 2.0.x Performance Fine-Tuning Technical Notes. (e.g. mdm_number_sds_receive_umt, sds_number_network_umt)

I could find how to change the values by changing its profile from Default to High Performance (and vise versa) but could not find how to change its each performance parameter. If anybody know how to change it, please let me know!
