Re: Frustrating network latency issue on NetBSD 6.1

[Greg Troxel <gdt%ir.bbn.com@localhost>]

  25 packets transmitted, 16 packets received, 36.0% packet loss
  round-trip min/avg/max/stddev = 1.937/2.639/6.781/1.253 ms

So it's pretty clear that your problems are due to loss and not delay;
all non-delayed packets were delivered with minimal delay.

The next thing I'd want to know is if the loss is in transmitted or
received packets.  To do that you'll need to be able to tcpdump on the
target, or get at counters. (Look at netstat -s; it's often useful to
capture netstat -s, do something, re-capture, and diff).
