Just wanted to say thank you for confirming a performance issue we saw as well! It's the first mention I've found anywhere about it and I was beginning to think we were going nuts.
In our case, it affected both HP DL380 G8 and Dell R710 hosts with NFS, FC, and ISCSI storage. Disk access times went to 500ms from 1-5ms for our guests. We found the same fix in rolling back to a pre-3/8/17 patch level.
Has VMware been able to determine a usable fix?
