slow network speeds (20mb/s) on ESXI 7.0 with 1.04b loader & vmxnet3/e1000[e] & dsm 6.2.3


Recommended Posts

So i've tested internal copies/moves between shared folders & doing a dd test via ssh and have not had any speed issues - however any transfers to and from seem capped around 20 mb/s regardless if if i use vmxnet3 or e1000

not sure where to begin to debug this, and while i could pci passthrough a 10g nic i'd rather have it talk to other VMs via the virtual switch. Anyone have any advice?

so plot twist: it doesn't see to be network:

by writing to the raid 5 array over cifs is capped at 20mbytes, but doing an internal copy between shared folders i get 100mb/s
