Hi,
I just bought LPC4357-DB1 board and am trying to improve lwIP through put. Can some one help me?

I'm currently using LPCXpresso v5.2.4 and lpcopen v1.03. I modified lpc43xx_hitex_eva_4350_tcpecho_freertos to work on Diolan board and and currently getting about 850KB/s throughput. I'm using 1.25KB packet to and from the target device. This is very slow compared to 95.0 Mbits/sec reported in this site. What do I need to do to make it perform better?

I'm already using MEM_USE_POOLS and disabled most of debug options. What configuration did you guys use to get the kind of performance you report at (http://www.lpcware.com/content/project/lightweight-ip-lwip-networking-stack/lpcopen-lwip-benchmarkings-and-timing-informati)?

Is there a guide to configuring lwIP with FreeRTOS that will give me maximum performance? As a comparision, my old platform which uses PPC405 GP gets 2MB/s running the same test. I was expecting LPC4357 to be much faster than PPC405 GP. I did some debugging and found even when I force the ethernet to work at 10Mbit/s (write 0 to MAC_CONFIG.FES), I get the same throughput. It seems that the ethernet is stuck operating at 10Mbit/s no matter what. Can some one help me figure this out?
