Re: Low capped TCP network speeds over the Internet

When I do similar things, I use "tcptrace" (in pkgsrc
net/tcptrace), which also produces input plot files to xplot.
"tcptrace -G <pcap-file>" will leave a number of *.xpl files in
your current directory.  For the most useful view, the pcap
should be captured at the sender.
