A common question we have is, “How does LightSpeed and Speed Booster differ and how do they compare to Magento Caching and AITOC Magento Booster?” The biggest difference is block caching vs. page caching.
Tiny Brick Speed Booster also uses block caching for Magento. Speed Booster automatically caches the most frequently used elements of your site, and configures them properly for caching. When you make changes to categories, products, CMS pages and CMS blocks individually, Speed Booster will recognize the individual changes specific to you and automatically reset the cache—for you.
