Hi
We are running kvm instances on omni r20 and are experiencing random short
freezes.
I wrote the following short test script to see how frequent the freezing
occurres
perl -e 'use Time::HiRes qw(time usleep); my $now = time; while(1){usleep
200000; my $next = time; my $diff = $next - $now; $now=$next; if ($diff >
0.22){ print "".localtime(time)." ".$diff,"\n"}}'
the output looks like this

as you can see there are quite frequent short freezes ...
I am running the same script in the omnios global zone there is no freezing
over 0.02s
any ideas ?
cheers
