Optimizing memory access with DPDK allocated memory

Let us say I have two memory channels each one with its own 16GB memory
module, I suppose the first memory channel will be used when addressing
physical memory in the range 0 to 0x4 0000 0000 and the second when
addressing physical memory in the range 0x4 0000 0000 to  0x7 ffff ffff.
Correct?
Now, I need to have a 2GB buffer with one "writer" and one "reader", the
writer writes on half of the buffer (call it A) and, in the meantime, the
reader reads on the other half (B). When the writer finishes writing its
half buffer (A), signal it to the reader and they swap,  the reader starts
to read from A and writer starts to write to B.
If I allocate the whole buffer (on two 1GB hugepages) across the two memory
channels, one half of the buffer is allocated on the end of first channel
while the other half is allocated on the start of the second memory
channel, would this increase performances compared to the whole buffer
allocated within the same memory channel?
