(Get the code!)
I can confirm this bug.
I use LUKS with ext3 on Kubuntu Feisty.
When I have moderate disk activity the system is almost unusable.
I think this is a scheduling problem.
Although extra computations are needed when using encrypted filesystems, these extra computations should not have such a high priority that it should be impossible to use the computer for audio, video, moving the mouse around, etc.
I have a 1.8GHz Pentium M processor. That should be enough to handle the extra computations needed for the encryption while decoding ogg audio or playing video.
