The throughput of phantun is only half that of udp2raw

Please provide more information such as your config and setup, otherwise this won't be reproducible.

I re-executed the test and added the test of the intranet environment

client environment info

location: China Mainland cpu: Intel Pentium Gold 8505 (6T)

aliyun server environment info

location: China HongKong cpu: Intel Platinum 8163(2T) connect: 100Mb/s Internet

E5 2686v4 server environment info

location: internal lan cpu: E5 2686v4(6T) connect: 1000Mb/s ethernet

Test Result

• aliyun server udp2raw server cpu usage 15%，client cpu usage (7%)，throughput 30.7Mb/s phantun server cpu usage 8.6%，client cpu usage(6.6)，throughput 31.7Mb/s

• E5 2686(6T) server udp2raw server cpu usage 90%，client cpu usage 70%,throughput 272Mb/s phantun server cpu usage 187%，client cpu usage 145%，throughput 439Mb/s

test again,saame environment as above, server is aliyun:

My conclusion is that phantun is better in a high-performance environment (cpu greater than 4 cores, bandwidth greater than 200Mbps), and conversely udp2raw will be better.

@haohetao That's as expected. With single core the multi core capability of Phantun becomes a disadvantage because of additional synchronization overhead to support it.
