What does the values in Speed Dev indicate
I have tried searching for the answer to this, I found a post by 'atom' saying he explained it in the release notes, but after reading the release notes I still could not find it.

I want to know what exactly does the values in Speed.Dev.#1 indicate?

For example I notice that for this value: Speed.Dev.#1.....:  9452.7 kH/s (6.63ms) d It shows that it would take around 6 days 9 hours to crack an MD5 Chap password of 8 characters. 

Please link me to the relevant guides and information.
