html sites are fast but cms (WordPress/magento) sites are slow on my server. I cant find the reason. This is my default WordPress site without theme and any plugins. Just installed. http://www.googlecloudhost.com/. It took 90+ seconds to load but this html site http://sohamdistributors.com/. This takes less than 2 seconds to load.
Please help me to find the reason of slow cms site.
Sites using WordPress/Magento are slower than sites using static HTML because of PHP and database usage. Your site on googlecloudhost.com seems slower than it should be though, it takes 20+ seconds for the server to respond.
To make sure the problem is not caused by a plugin you are using on your website you can use the Plugin Performance Profiler plugin for WordPress.
To increase performance you can also use a caching plugin like W3 Total Cache.
If both options do not solve your problem consider consulting your hosting provider, the problem could be caused by their setup then.
