Testing method used

Install two fresh phpBB 3.0.6 boards. Install automod (newest) on both.
On board 1 install nothing. This board is listed as the "before" board in the test.
On board 2 install social buttons network mod. This board is listed as the "after" board in the test

Clear all cache etc on the browser. 
1: Login to both boards. Surf around all the pages listed below so you visit them 5 times.
2: Surf around all the pages listed below so you visit them 5 times again. This time copying the performance info
in the footer for each page. 

REMEMBER. 
1: The time spent loading each page can vary alot from server to server. I use a laptop with xampp.
2: Queries are the same no matter where you run this mod.
3: Memory Usage can vary. The test below are done with eaccerator on. Dont expect your Memory Use to be the same numbers
-  This is also the reason i use percentage, it should be a more stabile factor no matter what server and cache you use.

The percentage was calculated in this fasion.
Example from index
before: 510.85 KiB
after: 519.63 KiB

519.63 divided with 510.85 = 1,0171870412058334148967407262406

1,0171870412058334148967407262406 minus 1 = 0,017187041205833414896740726240579

0,017187041205833414896740726240579 multiplied with 100 

Result = 1,7187041205833414896740726240579 %
