O_DIRECT would be better, memory size should not be the issue then,
more can device A and the CPU keep up with device B.

I would recommend trying it out on a regular box with this amount of
memory (use the boot options to trim it down) and a similar bandwidth
for data input and output before you invest a lot of effort into the
embedded setup.
