After the initial creation of your Virtual Machine there are a number of performance tweaks you can make to your Guest's .XML file and/or the Host system to greatly increase the Guest's performance.
hugepages
Hugepages are a function that lets the system kernel use larger pages when reading or writing information to memory (RAM). When this is enabled and the Guest is configured to use them the performance can be greatly increased. How to enable Hugepages depends on your GNU/Linux distribution.
Note: When hugepages are configured this portion of memory is taken away from the Host. This means the Host will no longer be able to use it. Keep this in mind.
