The VPS industry is mounting day by day. There are many solutions, many providers, as well as good offers in the souk.

One hindrance comes to the point when hiring a VPS hosting company: oversell. VPS means Virtual reserved server. That also means that you can build as many virtual machinery into one hardware server.

Usually an actual server like Opteron quad heart w/ 8GB RAM would handle no more than 20 VPS servers lacking a hindrance. But as there are many brokers in the souk, value happening to make the difference. And in order to decrease the decisive value, companies would overload their servers.

As a solution, many customers prefer Xen. This technology doesn't allocate overselling, and guarantees each and every server supply to the end addict. In the other hand, it's 20-30% more exclusive than a regular OpenVZ or Virtuozzo VPS solution.

The quiz is: is Xen truly merit?

First, the central difference between OpenVZ and Xen is that OpenVZ shares the OS PIDs between the reserved servers. You can see all the processes one addict is running, from the central hardware node. Xen doesn't.

The ...
... central gain for OpenVZ is the performance. with Unixbench, we have been able to note up to 40% more rush than Xen. Why does it occur? The minimal answer is that Xen needs to do a fulfill virtualization, creating a totality new scenario for the working technique. And that wastes some funds.

If you are planning to hire a VPS server in the next time, you should think this. It's not a statute that you must always all the funds 100% guaranteed, as you will drop CPU performance. In the other hand, if you won't must always the totality RAM open from the VPS hosting visitors, you can cleanly use OpenVZ with such performance gain.
