OpenLiteSpeed and LiteSpeed Enterprise intercept incoming HTTP requests and serve static, pre-rendered HTML snapshots from memory in under <strong>30 milliseconds<\/strong> with zero PHP-FPM execution.<\/p>\n<h2>Step 1: Enabling Guest Mode and Guest Optimization<\/h2>\n<p>Guest Mode is LiteSpeed&#8217;s flagship speed feature for first-time visitors and Googlebot crawlers.
