Performance

1. Server - Stress test - Loading of dominoExperts.com
This test loads our first page (35 requests) by 200 simultaneous users during one minute in MS Web Application Stress Tool. The test is performed over a gigabit link. The server is a one CPU quad core (Q9550) at 2.83 GHz.
The test downloads every request every time and ignores browser cache.

	DAP loaded	DAP not loaded
Number of hits/1 min	105 696	38 183
Requests per second	1 761	636
Total bytes for page	128 320	355 600
Highest average response time	141 ms	601 ms
Lowest average response time	71 ms	231 ms
CPU usage

Note how much lower the CPU graphs are, the DAP cache is clearly taking load off the server even though the server is delivering 1 125 requests more per second.

2. Web Client - Page load time test - Loading of dominoExperts.com
The load time tests were done using IE7 and Charles web proxy to measure timing and simulate the different connection speeds.
Load time for different connections.

	DAP loaded	DAP not loaded
Total bytes for page	128 320	355 600
Gigabit connection	1.14 sec	1.78 sec
100 MB connection	1.74 sec	2.48 sec
10 MB connection	1.95 sec	2.62 sec
256kb connection	4.39 sec	11.84 sec

Speed increases more for slow connections and would be more visible over a real internet connection where packets might even get lost and have to be retransmitted.
The reason the compression is not higher is because of the images on the page already being compressed.
