Vshare need a caching system for fast page loads. This is one of the main feature that PHP script must have. Every PHP script has this feature because when you run a popular website that uses PHP and MySQL you will most likely notice that your website becomes slow when your website is at its busiest. If you've really optimized your PHP script and MySQL server, you'll probably be able squeeze some additional performance out of your website, but there comes a time when it's just too much to handle. That's where caching comes in.

If you cache frequently visited data, and this usually includes your homepage, you can drasticly reduce your website's response time. By caching data to the file system, you completely cut MySQL out of the picture, and that is usually the biggest bottleneck. Another added benefit is that it will decrease the load on your MySQL server, making it faster for data that hasn't been cached yet.
