Accelerating WordPress sites with Redis, LiteSpeed Cache & CloudFlare Railgun

Written by Jo Stonehouse
WordPress is the most popular content management systems on the internet today, powering some 25% of all websites. From a personal blogging site to a full WooCommerce powered shop, WordPress is a smart choice due to its extensive choice of themes, ease of use and powerful features available thanks to the thousands of plugins that have been written for it.

Over 70% of the sites that we host which use a CMS, are powered by WordPress. It's popularity is staggering, and as such every day we handle a wide number of queries relating to WordPress, from basic how to's, through to more advanced debugging.

One issue that comes up from time to time is speed.

We've invested heavily in developing a WordPress hosting infrastructure that's as fast as can be - with PHP7, OpCode Caching, HTTP/2, super-fast SSD based disks and more. Compared to most hosts, our platform for WordPress already is super-fast. But nonetheless, there were still cases where some of our customers ran into speed issues, usually the result of there being too many plugins, poorly written plugins, or unoptimised themes.

Historically, to get faster speeds out of these sites might have involved an upgrade to a virtual or dedicated server, where we can use specialist caching solutions and also leverage more server power. However, thanks to the introduction of server side page caching and backend database caching on our business hosting plans, these technologies are now also available without going to the expense of running your own server!

If WordPress was fast before, these technologies turbo charge it.

Websites, at LiteSpeed.

We recently announced the addition of Redis and Memcached to our Business Hosting Plans, two of the most widely used solutions to accelerate database queries through caching.

Today, we're introducing another speed enhancing tool - LiteSpeed Cache.

LiteSpeed Cache can dramatically increase the speed of your website. This can have significant impact on your search engine ranking and also improve your user experience and the number of prospective customers your business converts.

Once implemented, your site will operate, quite literally, at light speed.

The performance is simply breathtaking.

Want more speed? You got it. Redis & Memcached are now available!

Get ready to enhance the performance of your database driven applications - Redis & Memcached have now arrived at Kualo!

The developers among you who have heard about these technologies will no doubt be incredibly excited to hear this.

But don't be despondent if you haven't the first idea what Redis or Memcached are - we'll explain everything to you in this post, and let you know how you can implement them.

And best of all, we're able to make Redis and Memcached available on shared hosting - both now included as standard with our Business Hosting plans.

Statement Regarding Hurricane Irma

Written by Jo Stonehouse
Update September 12: Hurricane Irma passed through Tampa without any disruption to our service. Normal operations have now resumed and new server provisions are once again possible.

With Hurricane Irma approaching Florida this weekend, where many of our U.S. based servers are located in our Tampa facility, we would like to assure our customers that every precaution has been made in preparation for the storm.

The facility that houses our servers was built with just this kind of weather event in mind, located 90ft above sea level in a hardened hurricane-resistant windowless bunker. The datacenter has 'critical infrastructure' designation with the Department of Homeland Security and City of Tampa, and as such has dual power connectivity to both the airport and hospital power grids.

Why you need to migrate your website from HTTP to HTTPS immediately (and how to do it).

Written by Jo Stonehouse
Since 2014, Google has been ranking HTTPS powered websites more favourably. But that wasn't enough for most website owners to switch their sites to the secure web, and the vast majority of websites still run over the insecure HTTP protocol.

But that should be set to change. From January 31st 2017, Google Chrome will start marking sites that collect sensitive information as 'non-secure'.
