[lwip-users] lwIP performance

[yueyue papa]

Hi All,

 

I make the 1.3.2 lwIP running in LAN environment.  My CPU is about 96M MIPS platform.

 

FTP client is used as a download speed test, the current speed is about 200k/s.  Is it a reasonable speed for lwIP?

 

I think the speed may be a bit slow, but I did not known the where is the problem.  I found the socket windows update will make the speed down heavily.

 

My performance tune process

1> pull mode ==> interrupt mode

     20k /s ==> 30k/s

2> removed some interrup delay and ...

    30k/s ==> 80k/s

3> CPU freqent from 48M ==> 96M hz

    80k/s ==> 180k/s

4> MSS 1K ==> 1460

    180K/s ==> 196K/s
