    Hi, I am new to VPS hosting. My problem is that my cPanel, WHM and website frequently go down. I use Verio as a host and they tell me that I am exceeding processing limits. Note that I have experienced far less downtime since enabling cache from within the content management system.

    Details: At any given moment I have around 25 users browsing my website. It is run on the latest version of the content management system Joomla.

    For this amount of users, loading very few photos, is it typical to be experiencing this issue? You can see my hosting package details here, Enhanced Plan: /http://www.verio.com/web-hosting/vps-virtual-private-server-2/

    Please let me know what other details you may need from me. Below is some extra data I thought may be necessary.
