Why can't a VPS utilize the full allocated resources?tarsick, most VPSs with dedicated ram actually run faster than dedi servers. The reason is that the servers that run VPSs are big servers that have high speed hard drives, and multiple-multi-core processors. Since most VPSs dont utilize the full allocated resources they can take advantage of the extra processing power and disk bandwidth availible from a high performace machine. Also most hosts will load balance their VPSs on their hardware so one machine doesnt contain many high resource using VPSs.

VPS is 1/3 the cost of a low end dedicated.. you get more CPU power than you would get from a dedicated that can be 3-4 times the price. In addtion, upgrading memory requires only a minute of downtime.. with dedicated it takes over 30 minutes.Thus,I suppose VPS is more advantageaous.
Also... Xen VPSs offer a more true private environment with full control over the kernel and control over your own iptables and so on.. Virtozzo/OpenVZ is not a private environment.. you are sharing the kernel with others. If there are any security issues, they are going to happen to all the VPSs on that server, where as with Xen, each VPS is completely encapsulated in it\'s own environment.
there is not different main diffrent is between resources..(ram,hdd,etc)What is the exact difference between dedicated and vps hosting? I have been told so many different things that I'm not sure what to believe. One person told me that its just a space difference while someone else disagreed
