[lwip-users] Bitrate with lwip

[ревунов сева]

Hi,

I'm using my FPGA-based board with this 
[http://electronix.ru/forum/index.php?act=attach&type=post&id=19682] 
realization of LwIP, but tcp-client's bitrate is very low (~4Mbit/s). 

My board is Altera DK-NIOS-2S60N based on Stratix II FPGA. I use NIOSII/s 
softprocessor without OS.  I use onboard LAN91C111 Ethernet controller.

Anybody tested this implementation and with which configuration 
(lwip-constants)?

Please note that I use NIOS processor, so it may be something like unusual 
environment for lwip.
What speed should I expect when using lwip ?

Thanks.
