How often we complaint of wordpress blog slow down and page loading time. The reason being is your Web hosting company. But that’s not true always there are something you need to do from your end before you ask your hosting company to look at the issue.
There are various reasons that your WordPress blog is loading slow and one of the simple reason is wordpress has to serve php call to open same page for different readers.
This add more load to server and should be avoided by using a cache plugin. There are many cache plugins available but one which I personally like and recommend for my readers are wp-super cache plugin. Wp super cache plugin stores your web page into .html format in cache folder and when a reader request those pages it serves from cache folder and lowering down the no. of php calls. This give an instant boost to your wordpress blog.
Even if you are not facing website slow down problem , wp–super cache plugin will speed up your blog.
Super cache is one must have plugin for any wordpress blog. Specially if you have high traffic wordpress blog and suffering from page load time issue, you should install and active this plugin right away.
