Fix Cron and Create PHP Cache for Top100 Site

My website [login to view URL] has a cronjob that runs every 5 minutes to update the status of Minecraft servers for each listing. I would like you to make it as efficient as possible as well as accurate. My last developer left me abruptly so I am left with a semi-broken site. For instance, the ranking page ([login to view URL]) works fine, but when you click on a banner, the profile information is incorrect. There is a problem with the cron job not updating the MySQL tables properly. Further to this, whenever you click on a banner, the profile ([login to view URL]) loads very slowly. This is because it is pinging the listed server and re-downloading information that should be cached by the aforementioned cron job. If you can deliver these fixes within 1 day, I will hire you and consider you for on-going work.
