To some degree this is to be expected. The ajax blocks load Drupal as an instance, so they will never be as efficient as a completely streamlined approach to returning content. Basically, Ajax blocks will be confined by the same behavior constraints of loading Drupal, HOWEVER, if you cache the rest of the page and only need to load Drupal for the ajax blocks, you still see improved performance vs. loading the entire page using Drupal.

Since I'm not really maintaining this anymore (it's for D6 and we're almost at D8), I'm not sure it's worth showing benchmarks, but try running an e-commerce (ubercart) D6 site without anything, then try it with boost & ajaxify_regions. The difference is readily apparent.
