I would like to add a few general comments:
- make sure to follow the “Fine Tuning ScaleIO” document at: https://support.emc.com/docu55407_Fine-Tuning-ScaleIO-1.3X-Performance-for-Flash-Environments.pdf?language=en_US
- if you are testing an HDD config, make sure to turn on Read Cache, if the config is SSD, please turn off Read cache
- if you have any sort of caching, please make sure to run a long enough test to warm up the cache. Depending on the cache size and type, it can take minutes (DRAM Cache) to hours (SSD cache).

Hello DanAharoni
Why read cache needs shutdown when test ssd?
