Re: [go-nuts] How to make UDP server performance better?

[Matt Harden]

The time spent in the syscall would include time blocked, waiting for a
packet to arrive. I would look at the other parts of the profile for
possible improvements. The kernel may also be dropping packets if there is
not enough buffer space to receive them into; see the SO_RCVBUF socket
option. Maybe ntpd sets this option to a larger value than the default.

[go-nuts] How to make UDP server performance better?

[Zhuo Meng]

Hi, Gophers

I'm doing benmarking for my GoNTPd   
.

I found that my implement is only can handle about 100Kpps (kilo packets 
per second) per goroutine while ntpd can handle about 170 Kpps. on Intel 
Xeon E312
The pprof shows most of function time spend on syscall.Syscall6 (Read/Write 
from UDP socket), how can I improve that?

Many thanks!
