Hi everyone

I am running DPDK sample application compiled in Fedora 14 environment.

I have used following command to run the App

./<application> -c f -n 4

c= bitmask of cores to to be used.

and

n= number of memory channels

Now what does 'n' actually defines ?. Is this the number of DMA channels between RAM (hugepages) and NIC. ? If not so then what it is ?

How does number of memory channels will effect the performance ?
