Re: [lwip-users] Speed of LwIP ?

[Craig Graham]

I've run Oregan's Interactor web browser (same browser shipped by SCEE for the 
Playstation2) using LWIP as the network layer, and it easily handles MP3 
streaming over TCP (HTTP). I've also got MPEG2 streaming working over UDP on 
LWIP.

Both of these things are running on the PPC405-cored IBM Stbx25xx "Vulcan" 
set-top box SOC - a bit faster than the ARM you're thinking about using 
(200Mhz), but it is running a web browser at the same time as the streaming 
with no visible impact on the performance of the web browser, so the system 
isn't exactly overloaded at these rates ;)

Laters, 
Craig.
