It may not be a software issue--could be a network configuration issue.  More
below.

After opening this in Wireshark (http://www.wireshark.org/), I see a lot of
packets labeled:

    [TCP segment of a reassembled PDU]

Doing a few Google searches, it looks like you may need to adjust the MTU (a
network configuration parameter for a wired or wireless ethernet connection) on
your wireless router and/or your Macs.  (Note that the "/sbin/ifconfig" command
will list the MTU parameter for each interface as well.)

I don't recall how to change this parameter on OS X off the top of my head, but
I'm sure a Google search will give some information.  For example:

http://docs.info.apple.com/article.html?artnum=303192

Not sure why your Macs would be affected while your PCs would not (assuming
they're all using the wireless connection).  Perhaps the MTU on the wireless
router needs to be adjusted (which will vary by router--most likely there is a
web interface to do this, though)?

BTW, try changing the MTU before running sample(1) per Comment #9 and Comment
#11.
