Performance of encrypted file sysstem

I need to know how much moving to an encrypted file system will degrade our systems.

In general, how much should a luks encrypted file system degrade HD performance (no specific hardware target)

Any links ?

Thanks

hd will not be crippled in any way.
As an indication desktop cpus before AES-NI did AES128 at 150MB/s
Now it is more like 1000MB/s with AES-NI

Say modern disk works at 100MB/s, so it will take 10% or 70% of CPU time to access disk at full speed.
