-----------------------------------
Hi [~sunilg]
Thanks for the pointer, I have run that perf UT
2 resources result:
* before: #ResourceTypes = 2. Avg of fastest 20: 44843.05
* after: #ResourceTypes = 2. Avg of fastest 20: 41841.004
5 resource result:
* before: #ResourceTypes = 5. Avg of fastest 20: 37950.664
* after: #ResourceTypes = 5. Avg of fastest 20: 31545.742
Not sure how to eval this result. Is it a concerning overhead?
