Our VPS are generally much faster than a lot of dedicated servers, and it has really nothing to do with bandwidth ...

Most of our dedicated servers are configured with RAID1, RAID0, or Linux software RAID ... but ALL of our VPS offerings use a 6-disk RAID10 redundancy ... so the disk I/O on the VPS is at least 300-500% better than a dedicated server with common 2-disk configurations.

With the shift in recent technologies, we have had many clients previously on a dedicated server, make the switch to a well-appointed VPS. And with Google giving the most love to sites that load quickest nowdays, you want as high an I/O rate as you can get!

Most of our clients who choose to stay on dedicated machines, are either A) old-school webmasters who still believe that VPS is only a bridge from shared hosting to dedicated -- or B) running scripts that require unconventional server configurations that cannot be setup on shared hardwares.

A large site utilizing a CDN setup, is also a series cluster server setups - similar to VPS.

That being said, yes you will in some cases see a much better speed with a VPS than you will with many dedicated servers, and it has really very little to do with the bandwidth.

Virtualization has improved so much in the past 5 years, that I have even unfortunately seen some "Dedicated Server" companies sell 'virtualized dedicated environments' as dedicated servers -- as they tend to be much more cost effective when you share the hardware with multiple users -- and 90% of webmasters will never know the difference or be any the wiser.
