I don't think it's possible to NOT use DMA on a 5200. If your link is 100Mbps and you are putting out something close to that then 90% is not unreasonable. There are still memory copies involved.
Where is it getting the large file from? Maybe IDE is a bottleneck.

Hi. I'm using linuxppc_2_4_devel from Denx CVS on a Lite5200 board. When doing "put" of a large file to a ftp server, ftp eats all the CPU available (90%+). I suspect it's not using DMA for the ethernet. Is this right? Thanks in advance.
