Excellent work, Carroll!  I'd like to see TASC or Futures publish something
this comprehensive.

Subject: Performance Analysis of Feeds


Evaluations are given here for Signal/cable, Signal/Internet (ESignal),
   BMI/cable, BMI/satellite, and S&P Comstock CSP/satellite.  Note
   that BMI/cable is very good, as good as satellite, whereas
   Signal/cable is ... (fill in your own favorite adjective).  The
   jury is still out on ESignal - actual performance at the user's
   end seems erratic.  We'll continue to look into this.

Performance data are determined for each half-hour time period
   during the trading day.  This provides a daily profile which
   can reveal patterns of poor performance.

Lag is difference between CME T&S time & collected time stamp
   (collected minus CME).  Negative times indicate something
   funny with either the feed time itself, or the process by
   which feed time is attached to the collected data.  This might
   also be due to an incorrect local clock if the time stamp is
   being set from the local clock.

Gap values are for the worst gap occurring in that time slot;
   length is in seconds.  Length of zero indicates that the 1st
   tick of a pair was dropped where both members of the pair had
   identical CME times.

For the following tables to be legible, do the following:

If you're reading this in an e-mail reader, switch to a fixed-spacing
font (in IE5:  View,  TextSize,  Fixed).

If you're reading it in Notepad, change the font to Fixedsys or
Courier (NOT a TrueType or any other proportional font).
