Hi All We have OpenBSD running in VMware 5.5 for about 2 years and recently 6.0. So over multiple OpenBSD releases.
It is stable and works, and we can use both em and vmx driver, but only get around 1.5 - 2.0 Gbit/s Example between two VMware ESXi 6.0 servers connected with dual 10G connections across Juniper EX switch root@skyfw-osl1-02:root# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 4] local 185.161.127.28 port 5001 connected with 185.161.127.29 port 8188 [ ID] Interval Transfer Bandwidth [ 4] 0.0-60.0 sec 13.1 GBytes 1.87 Gbits/sec client command: iperf -t 60 -i 5 -c What are other people getting from OpenBSD network drivers in VMware? Note: we also use OpenBSD as firewalls/gateways inside VMware and the performance is also less than expected for that. Note: same environment get almost full 10G wire speed from Ubuntu 14.04/16.04 etc. We are very interested in getting this performance up, so any ideas are welcome.
