Hello!
Me and a friend of mine decided to compare FreeBSD and Linux using this
little program (compiled with "gcc -lm")
Two identical machines run FreeBSD 4.0-SNAP 20000214 and Linux Mandrake
7.0 kernel 2.2.13
----------------------------------
#include <math.h>
double counter=0,counter2=32;
double
test()
{
return atan2(counter++,counter2+=counter*50);
}
int
main()
{
int t;
while((t=fork())>0);
if(!t) while(1) test();
else perror("fork");
}
----------------------------------
Well, after very short time, both boxes responded to console switchings
and things like that, but trying to run something like "ps", "w",
"uptime" put machine quite on hold (about 2 minutes). The thing is that
Linux finished runnig commands about 3 times faster than FreeBSD. What
the heck does that suppose to mean?! I thought FreeBSD whould kick linux
butt?
Please respond directly to me since I am not the member of this list.
Thanks.

Microsoft: Where do you want to go today?
Linux: Where do you want to go tomorrow?
FreeBSD: Are you guys coming or what?
A good conspiracy is unprovable. I mean, if you can prove it, it means they
screwed up somewhere along the line.
