Hi every body.
I have a Windows domain with a lot of servers (2012, 2016, 2019). All of the servers are virtual in vSphere 6.5
I have a 10 Gbps network and iSCSI 10 Gbps storage SSD and HD 10k. The SAN is new from 3 days :-) Before I had already 10 Gbps storage, no SSD.
When I copy file between 2 virtuals servers, I have ~300 Mo/s, not very good at all. It's better with this new SAN, but there is a problem.
I did many test and I find the problem. I use the security baseline GPO from Microsoft and the problem come from here !
In the MS security baseline, the data are encrypt, see capture :
If I disable all this value, my file copy increase to 700 Mo/s !
Can you explain me exactly what do these parameters please ? Is it very important to leave them enable ?
There is the same security baseline for the client computer in Wimdows 10 :-(
Many thanks for the explanation.
Best regards
