Boost provides static page caching for Drupal enabling a very significant performance and scalability boost for sites that receive mostly anonymous traffic. When there is no problem with your file system performance it is a good solution for shared hosting.
Since Drupal 8+ Version of this module Boost can serve cached content from files directly via RequestEvent independent from the used webserver. But it is still a good idea to use the webserver for serving static files. In this case there is even no PHP involved to serve content and get the maximal boost.
