I did a non scientific test of proxy performance using the script Stopwatch Please remember that this is a non scientific test where I don't have any control over the script, moreover the website performance might vary slightly between requests. I tried to do the tests one after another to get similar traffic conditions for all tests.
First, let me say that I didn't realize how light weight the proxy is without the av-scanner and without local content filter database. The av-scanner adds about 100 megs to the proxy and content filter adds another 300+ megs making it a resource hog at 540 megs with single AV and local content database.
Testing parameters: I loaded the site www.astaro.org twice without the proxy using packet filter to cache the DNS request and establish a baseline. I cleared the proxy cache and restarted the proxy between each test to clear any memory caching by the proxy.
The results are eye opening... With the local content database in memory and single AV scan enabled, the http proxy is almost 3 times faster on loading www.astaro.org. The screenshots are attached below.
Another interesting thing that I noticed was that the av scan slows down the proxy considerably when testing sites like cnn.com etc with a lot of graphics and external links.
