-You should be able to see the LiteMage cache page only took ''159ms'' to load. It was very fast and you can feel immediately. However when you look at the waterfall elements and overall loading time. It took around ''4s'' in total, which is normally the figure you will probably get from online speed checking tools as ''page load time''.

+The HTML page is the main page. It's the loading of this page that will give a general feeling of "fast" or "slow" to the end user.  LiteMage reduces the load time of the main HTML page from a few seconds to a //few hundred milliseconds//.
-You may notice there are a lot of static files such as css/jpg/js etc. LiteSpeed doesn't cache static file at all. If you have heavy static css/image files, They will take longer to load. Try switching to the lightweight template if you can. Enabling file compression, enabling browser cache or enabling CDN cache for static files should also help.

-If you scrolling down to time-consuming loading items, most of the time are Ajax call from either Magento code or some themes/extensions installed to you store.  Some was calling youtube.com, some was calling google api, some was calling facebook, some was calling external website hosted on a remote site with poor response time. All such Ajax calls are non-cachable and will make your store take longer time to load.  Reducing such Ajax calls from php code or changing to liteweight themes/extentions should help the overall page load time.

-Overall, with LiteMage's help, as far as the user sees the homepage within a couple of milliseconds instead of a couple of seconds, user should feel it very fast since they may not care if every piece on the homepage loaded or not. When the user scrolls down to browse,  the Ajax calls may have finish loading already.

+With LiteMage's help, as far as the user is concerned, the homepage loads within a few milliseconds. It //feels// very fast, since it often doesn't matter if every piece of the homepage is loaded at the beginning. By the time the user scrolls down to browse, the Ajax calls may have finished loading.
