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? is there any known issue in vboxnetadp? ------------------------------------------------------------ Client connecting to 192.168.0.60, UDP port 5001 Sending 1470 byte datagrams UDP buffer size: 9.00 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.0.1 port 48290 connected with 192.168.0.60 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 1.25 MBytes 1.05 Mbits/sec [ 3] Sent 893 datagrams [ 3] Server Report: [ 3] 0.0-10.0 sec 1.25 MBytes 1.05 Mbits/sec 0.039 ms 0/ 893 (0%) ------------------------------------------------------------ Client connecting to 192.168.0.60, UDP port 5001 Sending 4096 byte datagrams UDP buffer size: 9.00 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.0.1 port 58009 connected with 192.168.0.60 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 1.25 MBytes 1.05 Mbits/sec [ 3] Sent 321 datagrams [ 3] Server Report: [ 3] 0.0-10.0 sec 1.25 MBytes 1.05 Mbits/sec 0.100 ms 0/ 321 (0%) ------------------------------------------------------------ Client connecting to 192.168.0.60, TCP port 5001 TCP window size: 32.8 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.0.1 port 15490 connected with 192.168.0.60 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 447 MBytes 374 Mbits/sec -Howard -- -HowardReceived on Thu Sep 01 2016 - 07:06:09 UTC
