With Apache deflate (which is improved from Gzip) module you can quickly boost your site performance with some simple line.
You must use the IfModule statement to don’t break your site if the module isn’t supported.
<IfModule mod_filter.c> AddOutputFilterByType DEFLATE application/atom+xml \ application/javascript \ application/json \ application/rss+xml \ application/vnd.ms-fontobject \ application/x-font-ttf \ application/x-web-app-manifest+json \ application/xhtml+xml \ application/xml \ font/opentype \ image/svg+xml \ image/x-icon \ text/css \ text/html \ text/plain \ text/x-component \ text/xml </IfModule>
