SmartSniff shows the calculated speed of each TCP connection.

There are 2 new columns in SmartSniff utility: 'Last Packet Time' and 'Data Speed'
The 'Last Packet Time' column displays the date/time of the last packet captured for the specified connection.
The 'Data Speed' column displays the calculated speed in KB/Sec. This speed is calculated by using the 'Data Size' value and the number of milliseconds elapsed since the first packet of this connection arrived.

    There appears to be at least one small bug in the new feature. I've been using it a bit over the last few days, and it occasionally flips the sign on the data rate to negative. stopping and restarting the capture fixes this. (I'm using it just to generate traffic statistics, so I'm not retaining the capture data.)I've also had it throw exceptions a couple of times. Here's the exception data:
