I'm running a trial P1 license to see if I could deploy a CHR as border router. I have two interfaces, one externally facing and one internal. When doing some performance testing externally I get odd results. Download seems to be capped to ~100Mbit/s but upload works fine and I'm getting around 920-930 Mbit/s which is expected. This if for traffic facing outward. Internally running Btest between a RB1100Hx2 and CHR I get 970-980 Mbps in both directions. Same performance tests on the external network with the RB1100Hx2 and I get 920-930 Mbps.
The hardware is a HP DL360 G6 with a 10 GbE adapter (HP NC552SFP 10Gb 2-port Ethernet Server Adapter) running ESXi 6.5.0 Update 1 (Build 7526125). Anyone seen this before? Thinking the P1 license which is limited to 1 Gbps mixes things up when I in fact do have a 10 Gbps network connection on the actual server?
I've also tried to change adapter type assigned to CHR in Vmware but it dosen't seem to make any difference running the performance tests. When using the VMXNET 3 I see messages in CHR that autonegotation hasn't worked, I've tried disabling auto negotation and set 1000M full manually. When using e1000 as adapter auto negotation seems to work. Any pointers to what I could change to actually be able to fully use 1 Gbps both upload and download is most welcome!
Edit: I'm running the latest current, 6.42.3. I'll make new tests with bugfix only and see if it fixes the issue....
