[lwip-users] Typical order of performance for TCP on 16-bit uC?

[Leon Woestenberg]

Hello,

 

in what order of magnitude can I expect the TCP performance

to be in bytes/second on 16-bit microcontrollers?

 

Currently on our 18 MHz single-issue 16-bit microcontroller with

a CS8900a, my modified httpd.c delivers 22 KBytes/second.

 

All TCP and memory parameters are about 3 to 4 times the "minimal"

lwipopts.h configuration, and TCP_MSS = 128 (which is very low).

 

I am eager to hear if I am "ways off" maximal performance and what

parameters matter most to increase performance.

 

Best regards,

 

Leon.
