Why do we look forward optimizing a website ? The answer should be to correct problems that we have commit during the development of that website. Today someone asked me how to optimize his website, I figured later that his question was about caching !!
Now if you want to optimize your website, first thing to do is to detect the anomalies : it could be related to the design layer (images, html, css, … ), the software layer (possible coding bugs), or the database layer (bad indexing of your tables …). Make a first report of the existing, then a plan of possible solutions.
Here you can ask for example, if it is a software layer issue and you decide to use caching solution : which caching is the most suitable for your website. You can cache objects, pages, queries, depending on the solution that you are working on and depending on the server conditions. This is not all, because “caching” cannot always speed your website, sometimes it can make it slower !
There is a big difference between “I want to use caching solution” or “I want to make my website faster”. Before to decide what to do, try to ask what are you really looking for.
