improve tun performance via AF_TLS?
Context switch is still a great challenge for low-end CPUs. For recent linux kernels, it is available that new feature of tun driver , called NAPI. Obviously it helps somehow, though not enough for low-end boxes. Here I found some discussions within tinc community, which seems quite convincing. https://github.com/gsliepen/tinc/issues/110
I just wonder if anybody get some idea to improve it? Or some simpler way just to tweak kernel?
