I have 2 etch virtual machines. One's a clean Etch r9, the other is one of our server builds. On EtchR9 network speeds are 1Gbps. But on our server build we are only getting a max of 100Mbps, both network connections show they are connected at the same speed, same driver, same kernel.
I can test the speeds doing (ignore the ETA):
On the clean etch:
dd if=/dev/zero of=/tmp/zero.tmp bs=1M count=100; scp /tmp/zero.tmp fastserver:/tmp
Result I get is:
zero.tmp 100% 100MB 25.0MB/s 00:04
Which is fine, the network is being used but it shows the from my ESXi machine to another server (which is 1Gb, and a physical machine) I'm getting faster than 10Mbps speeds.
But, from a server build we get:
zero.tmp 100% 100MB 5.6MB/s 00:18
Both servers have the same kernel, same network driver loaded, same ESXi network settings. The physical links between the sender and the receiver are the same. I've tried rebuilding our server again and again but I keep getting these slow network speeds. The only solution I can think of atm is to try using the VMXNet3 Driver, but I haven't had any luck getting it to install.
While I don't expect a off-the-bat solution. Any tips on where I can check or look would be greatly appreciated!
