Two wordpress plugins to accelerate wordpress opening times and decrease server load time

A Comparison of wordpress webpage responce with and without wp dbcache

A combination of two wordpress caching plugins (Hyper Cache and Db Cachesignificantly improves the access times of a wordpress based blogs and websites.

Installing the two websites has drastically improved my blog opening times, so in my view having the two plugins on every wordpress install out there is a must! 🙂
The plugins installation is straight forward, here is how I installed them.

1. Installing Hyper Cache on WordPress

To install Hyper Cache all I had to do is download and enable the plugin, the plugin doesn’t require any configuration. I always love it when I don’t have to bother with reading configuration options and pondering for some 20 minutes on the plugin features, so in that perspective Hyper Cache in my view is a good alternative to WordPress Super Cache

Besides that WordPress Super Cache was having issues when enabled on few wordpress based websites I manage these days. For comparison Hyper Cache worked just great on all wordpress install I tried the plugin so far.

To install all I had to do is download the plugin unzip and enable it:

a. Download and unzip it

debian:/var/www/blog# wget http://downloads.wordpress.org/plugin/hyper-cache.zip
...
debian:/var/www/blog# cd wp-content/plugins
debian:/var/www/blog/wp-content/plugins# unzip hyper-cache.zip

b. Enable Hyper Cache plugin

To enable the plugin follow to standard plugin location;

Plugins -> Inactive -> Hyper Cache (Enable)

To enable the plugin follow to standard plugin location;

A  mirror of current version of hyper-cache.zip plugin is here 

2. Installing Wodpress Db Cache

What Db Cache, does it does caching of last queries made to MySQL for specified time, so if the query has to be refetched again from wordpress’s php frontend the queries results are fetched straight for the memory. This decreases the load towards the MySQL server and increases the webpages loading time.

As the plugin page suggests it’s way faster than other html caching-plugins like WP-Cache  or WP Super Cache

However, I think its still slower than using a combination of WP Super Cache’s alternative Hyper Cache  and  Db Cache . Combining this two could rise the webpage opening times according to some statisticonline at best cases up to 830% !! 😉 Let me proceed with how I did the install of  Db Cache .

a. Download and Install Db Cache

 

debian:/var/www/blog/wp-content/plugins# wget http://downloads.wordpress.org/plugin/db-cache.0.6.zip

...

debian:/var/www/blog/wp-content/plugins# unzip db-cache.0.6.zip

 

b. Enable the plugin 

 

Plugins -> Inactive -> Db Cache (Enable)

 

c. Make sure the permissions for Db Cache are correct

On Debian to enable Db Cache, the permissions should be changed for Apache to have a read/write permissions to plugin directory, on Debian to fix the permissions I used the commands:

debian:/var/www/blog# chown www-data:www-data wp-content

debian:/var/www/blog# chown -R www-data:www-data wp-content/plugins/db-cache

On other GNU/Linux distributions the above commands (user and group) www-data:www-data, should be set to whatever user/group Apache is running with, on Slackware this would be nobody:nobody, on CentOS and RHEL it would be apache:apache.

Finally to enable Db Cache go to

Settings -> Db Cache -> (Tick Enable) -> Save

I’ve also made a mirror of Db Cache plugin here

Enjoy the speed boost 😉

    By the way the Db Cache plugin is causing some wordpress installations I tried it to show empty pages instead of content. On some wordpress installs the plugin showed the website fine and did accelerated, however when trying to edit pages it returned empty pages.

    After a bit of research on the issues I realized there is a newer (modern) updated version of Db Cache which solves many of the problems of Db Cache. The superior plugin is called Db Cache Reloaded. Installing it and enabling it produced way nicer results and it seems so far the plugin is not breaking wordpress installs.

    With Db Cache Reloaded, I had some issues enabling it. The plugin complained about some duplicate class declarations. The only work around to make the plugin working is to select to use a Wrapper option from the settings plugins.

    I only recently realised the importance of caching. It can make a big difference. Thank you for these instructions.
