Boost - Static page cache:

(Not Recommended) Set Boost & Core (if enabled) cache for each page

Static page caching is a mechanism that stores dynamically generated web pages as HTML files in a special cache directory located under the Drupal installation directory. By caching a web page in this manner, the web server can serve it out in the fastest possible manner, without invoking PHP or Drupal at all. While this does provide a significant performance and scalability boost, you should note that it could have negative usability side-effects unless your site is targeted at an audience consisting mostly of "anonymous" visitors.

Из перевода можно сделать вывод, что при включении сего и при большом количестве анонимов, система будет тормозить. Может его не включать? Тогда зачем тогда Boost?
