I am using hobbitping and I am getting 43 seconds for 833 hosts pings.

PING test completed (833 hosts)          1157070413.072972         42.444355

Is there a way to improve number if  parallel pings by hobbitping  ?
my test hobbit server looks very low on load avgerage.

thanks for your pointer.
