I have a single site on my server with some requests using an incredible amount of CPU (almost 90%) Since the requests are about the categories inside the database and since the categories are always the same, I would like to get a software that could cache them and deliver the cached page instead of enquiring the database. Can anybody suggest me a software that can handle the caching of pages ? thanks in advance for your help.
You could try tuning up MySQL, query caching etc. settings. A php accelerator like APC will lessen the CPU load too.
