OK, I'll answer the question.
[Mar 23 02:34:41 UTC] Summary: 8 RC5 packets (42*2^28 keys)
0.00:55:36.03 - [3.33 Mkeys/s]
On Mar 23, your computer sent 8 completed RC5 packets back to a keyserver. Those 8 packets will count as 42 stat units.
It took 55:36.03 (55 minutes, 36.03 seconds) to do the work, which calculates out to 3.3 Million keys per second.
Since the best possible rate for a T-Bird is a multiple of 3.4, your T-Bird is running at an RC5 equivalent of 975 MHz, not quite up to your overclocked speed of 1200 MHz. Are you running a screensaver or playing video games?
Any other questions? Be sure to ask.
If you were doing OGR, your entry would look like this:
[Mar 23 02:19:26 UTC] Summary: 7 OGR packets (452.07 Gnodes)
0.14:34:51.99 - [8.61 Mnodes/s]
but it pretty much the same idea.
