Does LUKS encryption slow down the system?

How fast is the system after you encrypt / and /home partitions? Does anybody notice any difference compared to unencrypted partitions?

I'm thinking about encrypting partitions, but for speed reasons I don't know should I encrypt just /home or also the / partition.

I found nothing on LUKS homepage.

Technically it must be a little slower, but I never could notice it at all. If you do try it, watch top while you're working, the amount of CPU used by "kcryptd" is basically the amount of power you're giving up.

Thanks, I'll encrypt both then.
