Alternative PHP Cache, or APC, is a module for Apache servers that is employed to cache the output code of script applications. It is very efficient for scripts with large source code and will boost such an Internet site as much as 3 times. PHP websites are dynamic and whenever a website visitor accesses some page, the script connects to a database to get some content, then the code is parsed and compiled before it's shown to the website visitor. If the output code does not change however, that's the case with sites that show the very same content all the time, these actions trigger unneeded reading and writing. What APC does is that it caches the already compiled program code and delivers it whenever visitors browse a website, so the database doesn't have to be accessed and the code doesn't have to be parsed and compiled repeatedly, which in turn reduces the Internet site loading time. The module could be extremely helpful for informational Internet sites, blogs, portfolios, and so on.
