Drupal Performance - Boost Module: Research

I did a very simple test onBoost module to check whether it really has a significant performance upgrade.

I simply used 3 sites,

1. Site with Boost module installed
2. Site without Boost, but core caching is set to 'Normal'
3. Core caching and Boost caching off

Each site has Flags module with AJAX flags, 200 nodes with same content on every page(each node has 1 image), navigation block on every page and same theme.(Bluemarine)

Sites are setup on 3 subdomains under one domain, same host, each database with same environments.

I posted 200 nodes for each site(I simply copied entire database to 2 other sites, and configured Boost/Core caching)

Then I added 3 sites to Google Webmaster Central and verified. After 2 weeks, I came back to Webmaster Central and statistics for each sites.

Site without Caching by Core or Boost

Average Page Load Time : 1253 ms

Site with Caching by Core and Boost is disabled

Average Page Load Time : 996 ms

Site without Caching by Core or Boost is Enabled

Average Page Load Time : 225 ms

You can now see how Boost module is fast!

However you should refer Boost handbooks to configure it to suit your needs. Boost really can greatly increase your drupal site's performance, but make sure that it's set to best set of settings.
