-====== LSCWP Configuration Settings: Optimize ====== +~~REDIRECT>​https://docs.litespeedtech.com/lscache/lscwp/pageopt/~~
- +
-Optimize and [[litespeed_wiki:​cache:​lscwp:​configuration:​tuning|Tuning]] are two closely-related tabs. Generally-speaking,​ you will find the ON/OFF switches in Optimize, and the customizations that go along with these switches in Tuning. +
- +
-For a detailed explanation of what these tabs do, please see [[litespeed_wiki:​cache:​lscwp:​configuration:​minification|Optimization Through Minification and Combination]] +
- +
-**Please test these options thoroughly before enabling them on your production site!** +

-===== CSS Minify ===== +
-//off// +
- +
-Extra white space characters, new line characters, and comments will be stripped from all CSS, if this option is enabled. +
-  +
-===== CSS Combine ===== +
-//off// +
- +
-All individual CSS files will be combined into a single CSS file. +
- +
-===== CSS HTTP/2 Push ===== +
-//off// +
- +
-CSS will be sent to the browser before it is requested. +
- +
-===== JS Minify ===== +
-//off// +
- +
-Extra white space characters, new line characters, and comments will be stripped from all JS, if this option is enabled. +
-  +
-===== JS Combine ===== +
-//off// +
- +
-All individual JS files will be combined into a single JS file. +
- +
-===== JS HTTP/2 Push ===== +
-//off// +
- +
-JS will be sent to the browser before it is requested. +
- +
-===== CSS/JS Cache TTL ===== +
-//​604800//​ +
- +
-The minified and combined files are cached. This setting specifies for how long. The minimum is 3600 seconds, but we recommend 604800. When a ''​Purge All''​ command is issued, the minified and combined CSS/JS are included in that purge. +
- +
-===== HTML Minify ===== +
-//off// +
- +
-Extra white space characters, new line characters, and comments will be stripped from all HTML, if this option is enabled. +
- +
-===== Load CSS Asynchronously ===== +
-//off// +
- +
-Page loading can be delayed while waiting for CSS definitions to load. When you load CSS asynchronously,​ the contents of the page no longer have to wait for CSS to be loaded first. This setting also applies to Google Fonts. +
- +
-If you have critical CSS styles and definitions that must be loaded for above-the-fold content, you can specify it in the **Critical CSS Rules** box. +
- +
-===== Load JS Deferred ===== +
-//off// +
- +
-This setting takes all scripts and loads them only after the HTML is finished loading. +
- +
-===== Exclude JQuery ===== +
-//on// +
- +
-This setting excludes JQuery from all of the above optimization measures. It is recommended that this setting remain ''​ON'',​ particularly if you have inline JavaScript. If you are experiencing errors when **JS Combine** is enabled, turning this setting on should eliminate them. +
- +
- +
-===== DNS Prefetch ===== +
- +
-//OFF// +
- +
-Enable this setting to perform domain name resolution before it is requested. By prefetching DNS results, latency can be reduced significantly for your visitors as they click links, particularly on mobile networks. +
- +
-[[https://developer.mozilla.org/en-US/docs/Web/HTTP/​Headers/​X-DNS-Prefetch-Control|Learn more]]. +
- +
-===== Remove Comments ===== +
- +
-//OFF// +
- +
-By default, comments are preserved when JS and CSS are minified, but these comments can take up valuable space. Enable this option to strip comments from minified files and make them more efficient to transmit.+
