Re: [VBox] Extreme slow UDP performance between host and guest

Did you use the "-b" option to set the bandwidth it uses for UDP? It defaults to 1Mb/s, which is close to what you're seeing. Plus, I think the recommendation is that you use iperf3, anyway, and I don't think it has this quirk. On Thu, Sep 1, 2016 at 2:06 AM Howard Su

[VBox] Extreme slow UDP performance between host and guest

2016-09-01 Thread Howard Su
I used iperf to do a quick experiment on the UDP performance between VirtualBox and Guest through vboxnetadp. Guest is acting as server and Host machine is acting as client. the UDP throughput is only 1/350 of TCP throughput. Guest kernel is -Current and Host Kernel is 11.0-RC2. Anyone has idea?
