So now comes the disadvantages of using content management tools and systems. The main disadvantage is that with all of the Content management systems the new version keep on coming all the time. Also the hackers find out ways to exploit the popular content management systems. So you have to keep on updating at least once in 6 months if you want to keep safe. If you don’t upgrade you site can be hacked as the hackers can find vulnerabilities in Content management systems and can exploit those and then hack. Other disadvantage of using Content management systems is that you need to have a very strong server if you are using it. This is because all the pages extract data at run time from databases and if your database server is not strong your website will be too slow and sometimes can take too long time to load. This is a very major drawback of using Content management system. Also Content Management system infrastructure after installation creates a lots of tables for infrastructure install.
However some Content management systems however avoid this problem by caching pages. This prevents data to be loaded every time a page is loaded. You can set the time after which the data is refreshed. PHP have many open source content management system and code is freely available and customizable and the servers are usually very cheap so this hosting is quite cheap and this is the major reason PHP CMS are more popular and best CMS.
