I get a similar speed, but don't understand why. I would expect that given a 4-byte wide bus clocked at 33MHz performing a read from cache and a write into the destination userspace buffer, the buffer cache read speed should be more like 66MB/s. Is there another read/write pair that I've overlooked?
