We are working on getting our new CHR's tuned and configured. We have used the bandwidth test to the internal loopback interface with good success. We are getting different results on testing between the 2 different CHRs. Is this to be expected? We have tried disabling VMQ, offloading, upping the queues.
Loopback test
ESXi
100% CPU Load
62Gbps receive throughput
Hyper-V
100% CPU Load
