Hi,   when running dsm 5.2 on esxi systems, the copy speed is terrible slow   for example   if i copy over like 100 gb over gb network, it starts good at like 110MB / sec, but after a few min , it drops to 5 MB and eventually windows stops copying   changing from e1000 to vmxnet doesnt make any difference   running on baremetal, then there is no issue   what are the tweaks for this copy speed? to make it normal ?   i had an asrock mainboard, now i switched to hp gen 8 microserver
