[LAU] encryption and performance penalty

[Atte]

Hi

I'm thinking about protecting my data with encryption. I know it's a
complex matter, and very hard (impossible?) to make a system 100%
protected. And I must admit I don't fully understand the technical
workings of the various available tools, but I found
https://wiki.archlinux.org/index.php/disk_encryption.

Now I'm wondering:

1) Can anyone share hands-on experience with a particular strategy, why
did you choose that particular tool, is it easy to setup and work with
in every-day use?

2) Most importantly: How will the various methods affect my systems
ability to perform under realtime conditions (jack) including
reading/writing files from a DAW?

NB: I'm running debian stable, if it matters...

Cheers
