Hi,
I am setting up the FSS within 3 projects, my understanding is that if I have
project a=1 share b=2 and c=3 , then the cpu amount if there is contention
should be c=50% b=33% and c=17%. Server is a E2900 with 8 cpus.
When I run a test using the following code
foreach $i (1..30) {
$pid = fork();
last if $pid == 0;
print "created PID $pid\n";
}
while (1) {
$x++;
}
Where 1..3 = project a , 1..60 for b and 1..120 for c , I would assume that I
would hit the limits for each projects shares and see from prstat -J the
correct limits being attained. Can you adivse wither I am looking at this
incorrectly? or are the tests I am using flawed?
