I made a twice faster udpspeeder than the author`s, please enjoy it ,but I only compile the amd64(linux) version.
It should be used in server and client both sides. Can`t one side use mine and other side use authors.

速度提升怎么做到的 能看看代码吗

还有为啥这么小，不敢打开

[lls2wow]

@Smallthing 用的avx指令集，这么冷门的玩意还怕我加东西呀，郁闷

[lls2wow]

@Smallthing 这么小你也可以做到 linux下有个strip命令，你自己编译一个官方版本的 然后用strip处理一下就这么小了

哦哦 avx的话 arm路由器就用不了了 只能x86对接x86

Good job.
看来我也得去编译一个

I made a PGO optimized version. But I don't know how to benchmark its performance against GitHub release binary.

Method:
Strip all optimization related flags.
Add -fprofile-generate flag.
Build pre-PGO binary.
Run iperf3 for a while.
Build post-PGO binary with -fprofile-use=*.gcda -Wno-error=coverage-mismatch -fprofile-correction

P.S.
I really don't understand what -Wno-error=coverage-mismatch and -fprofile-correction will do.
I just saw them were added in this thread:
https://forums.gentoo.org/viewtopic-t-938468.html

P.P.S.
Use pre-PGO binary against real-world workloads.
You have to run iperf3 (or anything you want to run inside the tunnel) on your VPS.
If not, PGO feedback might harm the overall performance of the final build instead of improving it.
