A quick i/o test on 4.6.0-rc7 showed no difference in throughput between 4096-byte reads and 68-byte reads @ 1.5Mbaud in raw mode. Both averaged around 144Kchars/sec, or 96% b/w saturation, on a not loaded BBB. NB: the i/o test ran on a single BBB with uart4 sender to uart5 receiver. IOW, I would expect similar results at full-duplex.
