If you've ever wondering just what snowflake is doing to the display, t30dpy can accumulate some statistics:
Video driver is x11
48257100 points drawn in 66 total seconds, 731168 points/sec.
1998 total frames, 30 frames/sec.
0 frame late events, max delay 0 msecs.
694078 received points
10516 received points/sec
27466 maximum active points
0 points dropped because active-point pool exhausted.

The one that's directly related to snowflake is the received points/sec, that's directly tied to the number of IOT 7 calls being made. That corresponds to 368 milliseconds being used by the IOT itself, since it takes 35 usecs/point.
The 7,311,168 points/sec is how many actual pixels t30dpy is writing to the display, large because of all the dots that are in the aging process.
As a point of reference, the Type 340 display going full out drawing a lot of long vectors can hit about 500,000 points/sec being sent. The number of drawn pixels is stunning.
Well, I thought this was kind of interesting, but I clearly have issues. :)
