This is an interesting benchmark.  However the comparison as given
doesn't quite show the whole picture.  If you look at the size of
the "a.out" file produced, you will find (at least I find on our
UTS system [IBM 4341]), that the \smallest/ a.out file you can get
from UTS is ~20K bytes.  Once you drag any routine from "stdio" in,
it appears that an incredible gob of "in-laws" come with it.  This
may in fact be a disadvantage to UTS, but it does indicate that that
sucker can do I/O \fast/.  I think the basic filesystem block size
is 4096 bytes, which may help explain it.

So just comparing real/user/system times for "cc hello.c" may make
UTS/470 look good, but if you compared the time per byte of output
produced, it would make it look even better.

What a pity you still have to edit using those %$@!^@$$!  3270
tubes!
