What would be the Read-/Write-overhead when using dm-crypt (LUKS) as full disk-encryption (including root partition) on a Linux-Desktop (Ubuntu)? I plan to stack it like so: LUKS > LVM > ext4 The CPU in use on the system would be a Core2 Duo 2.1 GHz with 4GB of RAM.
- Would encryption of such a system create a great/noticeable overhead?
- Are there any recent benchmarks to be found on the net? What is your personal experience?
- Are there any settings I can make to improve performance?
Thx for your help.
