Nope, but there is something interesting to see from the ping statistics while this is going on:
118 packets transmitted, 118 received, 0% packet loss, time 117123ms
rtt min/avg/max/mdev = 42.022/158.507/720.719/168.475 ms
(Obviously this also covers some time before and after.)
Curious as to why my ping time goes up to several hundred ms while xterm is launching, I've discovered that this local machine feels the need to send a few megabytes of data to the remote machine before doing anything.
In fact, it looks like xterm is the culprit here. I don't have many X clients installed on the machine I'm ssh'ing into to test with, but xfontsel at least starts up a lot quicker (a couple of seconds).
If even xterm can't get X network transparency right, what hope is there for everyone else?
