Overview

Surge generates and serves static HTML files for your WordPress site, causing quicker requests, faster load times and a shorter time to first byte (TTFB).

Surge does not require configuration, and has no options. It works out of the box on any well-configured hosting platform. Cached files are stored on disk, and automatically invalidated when your site is updated.

In various load tests, Surge has shown to easily handle 1000-2500 requests per second at 100 concurrent, on a small single-core server with only 1 GB of RAM. That’s over 70 times faster than a stock WordPress install.

Impressed!

Thank you!

Surge: Zero-Config Powerhouse – Instant PageSpeed Boost!
by Marko Dimitrijević·10 months ago

Absolutely blown away by Surge! This plugin is a game-changer for WordPress performance. I saw an instant boost from 74 to 78 on PageSpeed Insights compared to another caching plugin, simply by activating it. The claim of generating static HTML for quicker requests, faster load times, and a shorter TTFB is spot on.

What truly sets it apart is the zero-configuration – it just works out of the box, making it incredibly user friendly. The load test results mentioned are impressive, and it’s clear this plugin delivers on its promises. Huge thanks to Konstantin Kovshenin for this fantastic, no-nonsense performance solution!

A tiny caching plugin that works and needs no adjustments!

I wanted to extend my deepest appreciation for your invaluable contribution. Your Surge Cache plugin has revolutionized the performance of my website. Amidst the challenges of compatibility issues between FlyingPress and WP Rocket with Sucuri WAF, your plugin emerged as the beacon of hope.

Previously, grappling with other caching plugins led to severe CPU spikes, pushing my site to the brink of breakdowns. While perfmatters provided some relief, I still needed a lightweight page cache plugin to navigate peak traffic periods seamlessly.

Enter your Surge Cache plugin.

Its seamless integration with my site has not only bolstered its speed but also its overall performance. I am now confident that my website remains steadfast and responsive even during the busiest of times.

Thank you, from the depths of my heart, for crafting such an exceptional tool. Your unwavering dedication to enhancing website functionality is truly commendable.

With warm regards,

Greg

Hello, for this plugin to work must the fpassthru function be activated or not? There is a difference?

Finally a Caching Plugin I can get behind!
by Jason LeMahieu (MadtownLems)·2 years ago·1 reply

Over the years, I’ve looked at all the top caching plugins, and never found one that I liked. They were either too complex, too finicky, or tried to do too many things.

Surge just works, and it works great.

Update: I ran some basic performance testing of the same sample content with and without Surge activated.

Surge increased my Requests per second by a factor of 21x and reduced my time per request by a factor of 25x.

Beyond that, Konstantin has been amazing as far as support goes for a free plugin. Besides addressing issues and requests, he’s gone above-and-beyond at helping work through issues, to the point of looking at where we are using Surge and making additional configuration recommendations. If it were possible to give 6 stars, I would!
