It depends greatly on your setup. Paravirtualized I/O (/dev/vdX) and raw
volumes (or LVs) will give you nearly native performance. As long as you
are using paravirtualized I/O you will probably not notice the difference
unless your server is very heavily loaded. Also, unless you have a lot of
spindles or are using fast SSDs, your disk I/O is more likely to be the
weak point anyway.
