Computationally expensive

Open amintnt opened this issue 4 years ago • 4 comments

Hello. kcptun is highly expensive in terms of cpu usage. How can I optimize it? I just need to forward a large number of tcp packets to another server through a udp tunnel and I don't care about encryption (so already set encryption to none). Any suggestions?

you can also disable FEC by setting -ps 0

I did a quick test, it practically makes no difference, the test results are basically the same (with marginal differences), roughly 40Mb/s at 100% CPU(crappy vps), with -ps 0 or default.

Can confirm in log the parameter is set correctly:

use hardware accelerated encryption algorithm, eg: aes

I’m using none in both tests.
