It should not. However it depends on how you set it up. Can you share
how you setup dom0 and domU, in particular CPU and memory allocation?

A "good" dom0 setup would tipically :
- has its own dedicated CPU (usually dom0), not used by domUs.
- has enough memory (512MB would do)
- not running any unneeded services (e.g. not running nfs server, http
server, etc.)

This is bad. Are you perhaps running lots of services on dom0?
