[Click] Performance questions

[André Campos]

I'm running a simple router (like fake-ip-router) using version 1.4.3 in linuxmodule on a P IV 866 MHz. My NICs don't have DMA and I'm having performance problems I think because of that. Running the router with InfiniteSource and DIscard in the place of From & ToDevice I more then 400kpps. In the other hand, when I use From & ToDevice I get only about 75kpps. 
 
 I think the NIC's are taking too much of processor time because of the lack of DMA. Does it procede or it's just me thinking wrong? I'm no hardware specialist so this is just a wild guess. 
 
 But as the only change is the insertion of the NIC's in the process I have to think it's a problem with them.
 
 Any help at all is welcomed
