Huh, Unix I/O is fast? I still remember good old times. Unix Sys V was at
least 5 times slower on a PDP-11 compared to RSX-11M. The reason? Unix used
an incredible amount of buffers mounted on buffers. An input character
travelled through 3-5 buffers before it landed in the program. RSX-11 I/O
was in-place with user-space single buffer passed to the driver. I think
the present situation is only worse, but there is nothing to compare with
(nobody would count Windows as a contender).
