- Subject: [ECOS] Problem of eCos 82559 Ethernet Driver Performance
I have a system with MIPS processor(RM7000), two i82559 ethernet controller.
I had ported eCos to the my system.
But, ethernet performance is so low.
So, I improve i82559 ethernet driver for removing memory copy.
But, the performance remain unchanged.
The performance was about 20Mbps while the system operation was bridge only.
I think, problem is that. BSD tcp/ip stack is so slow. or, the TX routine of ethernet driver is so slow.
What is problem?
