- If your webserver is properly configured to handle compression (gzip or deflate) and cache expiry (expires and cache-control with sufficient cacheability), you don't need Autoptimize to handle that for you. In that case you can check the "Save aggregated script/css as static files?"-option, which will force Autoptimize to save the aggregated files as .css and .js-files (meaning no PHP is needed to serve these files).

76
-
77
- Based on earlier feedback received from BuddyPress users, CSS and JS-Autoptimization do not seem to work correctly, leaving you with only HTML optimizations. This might be due to problems in Autoptimize which have already been fixed, so feel free to give it a shot anyhow.

  Autoptimize speeds up your website and helps you save bandwidth by aggregating and minimizing JS, CSS and HTML.

  So the choice should be based on your answer to some site-specific questions; what is your site's bounce rate? How many pages per visit do your visitors request? If you have a high bounce rate and a low number of average pages per visit, inlining CSS looks like a good idea. But with a high number of pages/ visit, it's probably not a good idea. Except if all you care about is a stellar PageSpeed-score, off course.

60
+
61
+ Autoptimize does not have its proper cache purging mechanism, as this could remove optimized CSS/JS which is still referred to in other caches which would break your site.
62
+
63
+ You can however keep the cache size at an acceptable level by excludinng JS-variables (or sometimes CSS-selectors) that change on a per page (or per pageload) basis. You can read how you can do that [in this blogpost](http://blog.futtta.be/2014/03/19/how-to-keep-autoptimizes-cache-size-under-control-and-improve-visitor-experience/).

  = What can I do with the API? =
66
 
67
  A whole lot; there are filters you can use to conditionally disable Autoptimize per request, to change the CSS- and JS-excludes, to change the limit for CSS background-images to be inlined in the CSS, to define what JS-files are moved behing the aggregated on, to change the defer-attribute on the aggregated JS script-tag, There are examples for all filters in autoptimize_helper.php_example.
