Switched WP Super Cache to Quick Cache

We have switched over from WP-SuperCache to QuickCache as the primary WordPress caching plugin for our site. We have used WP-SuperCache for over 5 years now and it is one of the best caching plugins out there. But then Quick Cache turned out to be a great caching plugin too

Remove WP-Super Cache

However, since the release of the latest version, there were some buggy issues and we were unable to delete the cache. It was getting tedious to FTP inside the server and manually delete the cache. Then repeatedly reinstalling the plugin, some strange kind of 403 errors occured. It was time to try a new caching plugin…

Kindly note these are isolated issues affecting only our server and WP-Supercache is undoubtedly an excellent plugin, which is not only the most popular plugin, but also highly recommended.

WordPress Caching

A caching plugin is the single most important plugin to add to WordPress blogs, as it stores php pages as html files and minimizes server load. It will keep your site online even when the server is down, and will help your website survive unexpected traffic spikes even on shared hosting.

I wanted to use W3-Totalcache and combine it with a CDN service like MaxCDN (or Amazon Cloudfront which we already use to cache some static files), but since the plugin is so feature rich and so powerful, the controls and options in the plugin are too overwhelming. Meanwhile, the forums are filled with growing popularity of QuickCache. So I decided to give QuickCache a try…

Install Quick Cache

Firstly QuickCache works out of the box. Simply activate and turn on caching and you dont need to edit any setting unless you want to really customise caching options, which we didnt need, not will most other users. So basically it was simple to start and get working instantly.

At most you might want to increase the caching time from default 3600 (1 hour) to 36000 (10 hours) or higher if your content does not change too frequently. Also note that QuickCache does not cache pages for admin and known users by default, and also refreshes the pages after people post comments. So you need to actually logout to see it is working. Another good option is it will refresh only the single post after edits, and not the whole cache ( for which there is a quick clear cache button on top).

If you FTP inside the server, the files in the /cache folder are also stored differently. While Supercache used to replicate your entire site structure in the folder, Quick Cache stores them as MD5 hash files, which checks with your Salt in a complex interaction before serving cached files.

Quick Cache  Gzip Compression

Note that unlike Wp-Supercache, QuickCache has no option to enable gzip compression of your webpages. Gzip compression is a good idea as it helps to compress pages and deliver them to modern browsers, which helps to speed up you site load times and deliver a faster and better user experience.

Quickcache FAQ does suggest 2 ways to activate gzip compression manually. One is by editing your .htaccess file using mod_deflate, but that did not work for our site. The other alternative did work as Knownhost has installed zlib on our server. Simple create a blank notepad file, add zlib compression

zlib.output_compression = on

and save as php.ini and upload to your server root folder. It works and pages do get gzip compressed. Since it does not output ‘gzip on’ comment in the html code, you can test it using any HTTP compression test tool.

So basically we are very happy with QuickCache as of now and it is caching our WordPress blog error free and it is also highly recommended. Are you using Quick Cache and have some tips to share?

    At the moment, I have not got any issue with SuperCache. Honestly, I have just switched from W3 Cache since the hosting provider staff recommended that. I also have no problem when trying to delete cache.

  2. QuickOnlineTips says:

    Daniel – its an isolated issue which we have not been able to fix. We have successfully used Supercache for over 5 years and it is very good.

    Quick cache is what I use, it handles more traffic , faster, more sturdy, lighter on cpu and ram.
    I used W3 Cache for over a year, then switched to super cache for a year or so. Been using Quick Cache for over a year too. It really depends on your environment, so you have to see for your self which is the good one. They’re all top cache plugins. But Quick Cache to me is the best!
    W3 Cache and SuperCache have crashed on my site a few times but never with Quick Cache.

  8. Harsh Maur says:

    I was looking for a caching plugin, I think the newest one i.e Hype Cache is one of the best and the fastest!

  9. Jim says:

    I will be staying with WP Super Cache. The problem with Quick Cache is that it does not cache compressed files. Even if a page is cached, it is still compressed on the fly for every connecting user, which is bound to increase your server load. COmpression is highly CPU intensive.

    Super Cache on the other hand just does the compression once, then just sends the same gzipped file each time. My testing shows that fetching a compressed page with QC actually takes longer than fetching the uncompressed page. Turn on compression with Quick Cache and your blog may actually slow down.
