I haven't run this query in a while, and I figured I'd share with all.

For yesterday, 23-February, we had 16,784 calls.

Bytes In: 1965002846
Bytes Out: 14169347010
Seconds Total: 27873365

So, by finagling numbers:

(bits) (kbits) (per sec)
((1965002846 * 8) / 1024) / 27873365 = .55 (in)
((14169347010 * 8) / 1024) / 27873365 = 3.91 (out)

So, the average user, during his session, is averaging 3.91 kb/s.

This hasn't changed for us for many months (1.5 years?).

I am curious what others are seeing.

So, on a fully loaded PM3;

(46 * .55) + (46 * 3.91) = ~205 kb/s.

Also, a good trivial number; what are people seeing for average session
length? We are seeing ~27 minutes (down seven minutes from 1 year ago).
