Chris,
If you don't already have this set, could you try activating the
high-res timer?  By default the system timer is 10ms (100 Hz) but if
you set the following in /etc/system:

set hires_tick = 1

it changes to 1ms (1000 Hz).  Among other things, this affects sleep
and wait calls which might be artificially inflating latency in
programs like ping.
