How do Unix and VMS compare?

[mcdermot at unmvax.UUCP]

One question Sean Casey asked about Unix vs. VMS was speed of VMS
FORTRAN against Unix C.  I did just such a comparison some time ago
comparing machines with 10 users each (the unix was 4.2BSD) and I
found little difference in run time of compute oriented jobs.

I/O, however, is quite a different story:  I ran these little programs
and found the C to be about 10 times faster than the FORTRAN!  This just
points out how poor FORTRAN's I/O system is, though, and was primarily
used to convince some friends to get a unix machine (they do a lot of
I/O so this was really important).


	program iobench
	do 111 i=1,65000
	write(6,61)'aaaa'
   61	format(a4)
  111	continue
	end

main(){
register int i;
	for(i=1;i<=65000;i++)
	  printf("%s\n","aaaa");
}

Hope this helps,
john
