Why should krfb use so much cpu when I never use it?

I was playing around with KSysGuard and I noticed the process using the most cpu was krfb, which is the server process for desktop sharing. I never use desktop sharing so I suppose it is a default loaded process.

Why would this process use so much juice (around 15%) when I never use it and it really shouldn't be doing much of anything? I don't see any network activity so I don't think I am being hacked.

I have suspended the process and nothing bad seems to have happened. Can I assume this is a safe thing to do?

Disable Ethernet permanently to speed up boot time

I do not use the wired Ethernet Card. It seems to me that, Ubuntu is always trying in boot time to check the network via eth0, Which consumes some times and I guess this may slow down the boot process a bit.
