The DMA is capable of transferring one word per clock cycle, if the memory is fast enough. If used with a memory controller that can do bursts, it will probably manage to reach this speed, after an initial latency. In your case it will be the CPU and the TCP/IP stack that will be the limiting factor. I still think it should be able to reach this speed though. If you start having problems, check that you are compiling the software with optimisations (-O2) as it gives the TCP/IP stack a significant boost.
