Magento Dynamic Caching Now Available!

Dynamic Cache for Magento

UPDATE: April 23 2018. The SuperCacher service does not support Varnish anymore. We use NGINX on all our platforms.

UPDATE: June 25 2015. The SuperCacher service for Magento is now available only on our Cloud Hosting and Dedicated plans.

If your site cannot handle all your visitors or is too slow to display your goods & services, it would matter very little how much effort you put in creating a beautiful storefront and comfortable customer experience. We know that many Magento users have to go for expensive hosting solutions in order to avoid possible performance issues. Not with SiteGround. We are happy to have significantly increased the number of people successfully using and growing their Magento websites on a shared hosting platform with the help of our newest addition to the SuperCacher – the Varnish-based dynamic cache option for Magento stores.

Varnish Caching for all!

SuperCacher for MagentoWhen we first launched the dynamic Varnish-based caching, it was available only for users running their websites on WordPress and Joomla. We have seen such impressive performance improvements that it was only logical to start working on a Magento implementation, as this is the third most popular application used by our customers. Some of you may have already seen and used the new option in the SuperCacher interface, as it has been in testing mode for the last few months. As of today it is now officially available for all customers on GrowBig and GoGeek plans, using the popular e-commerce CMS Magento. It is located in the SuperCacher interface in your cPanel and it works by storing a copy of your dynamically-generated content in the RAM of the server, thus greatly speeding up the overall performance and reliability of your site. You can learn more about the basics and how to enable this solution in our Dynamic Cache Tutorial.

This new Magento specific option comes in just a few weeks after we made the basic static caching (also based on Varnish), which creates a copy of all static content such as html files, Javascripts, and images, available to all our customers irrespective of their plan.

Magento Caching Plugin With a Twist

The Plugin InterfaceIn order to make the dynamic cache available to our Magento users, we have developed a special plugin, which should be downloaded and installed on your Magento as part of the caching activation. You can refer to our step-by-step tutorial on how to install SuperCacher on Magento and switch on the cache. We highly recommend that you i) make a backup of your site before you activate the dynamic cache option; and ii) examine carefully all sections of your shop after you have the cache running in order to make sure it all works fine.

If you do not feel confident enough to perform the installation and setup on your own or if you notice any issues or unexpected behavior, do not hesitate to get in touch with our Magento experts on live chat or ticket – as always they would be glad to help you.

    I have CDN (Cloudflare) enabled for my Magento website. Will Dynamic Caching cause any conflict with the CDN? And will there be a noticeable performance boost?

      Hello Jeremy,

      It's great that you are already using the CDN option on your website. Switching on the dynamic option of the SuperCacher should not result in any issues as the two tools complement each other. (Do make sure to make a backup of your site before you enable the dynamic caching though.)

      When it comes to performance, your site should definitely work faster, but there is no way to say beforehand. So, the only way to find out is by testing and comparing the load times of your website with and without each option.

      I hope that helps, let me know if you have any other questions!

    Where is the download link for the SuperCacher plugin.
    Also, do I have to turn off Google PageSpeed?

      Hi Luiz,

      You can find the download link in the SuperCacher interface under the "Level 2: Varnish Dynamic Cache" tab. If your installation is not listed in that tab, use the "ADD application" link underneath to add your site and get the link to download the plugin.

      Unfortunately Google PageSpeed is not compatible with our Varnish-based caching, so if you want to use the dynamic option, you would have to switch the Google module off. In any case, I would recommend that you give it a try and see which option makes your website perform better.

      Let me know if I can help in any other way.

    Hi llia,

    I have a ticket with siteground team, maybe you can help me.

    I'm using in my site the 3 supercacher level, almost everything is ok.

    I'm using a 3rd theme, my compare list is not working correctly, when my page is cached and I've added a product into a compare list, the product internally is added but my compare block still showing an empty list.

    Remembering, if I turn varnish off, the compare list work well.

    I guess that there is some specific point in my block that is doing the varnish to cache my block.
