Vmware paravirtualization drivers

Most of my infrastructure runs on VMware. I have the VMware Tools installed for all of my UCS systems
Are there any performance gains to be had by using the paravirtualization drivers for the HDDs? Are there any problem with using them?

There is no official perfomance testing for this specific environment at the moment. The usual remarks for Debian-based guests inside VMWare will apply.
I found one interesting note regarding the paravirtualization drivers on http://vmfaq.com/entry/25/:

From my experience at various VMWare driven environments the major bottlenecks are outside the Linux-guests, but thats probably something you already aware of.
Other readers may find useful remarks in the document quoted above.
