What will be the performance impact on my Celeron 1.73 GHz CPU and/or hdd speed?
Well, the usual "it depends on your [exact] environment" is the real answer.
However from a subjective perspective I've found that the only time that I've really noticed a performance impact is during lots of I/O, such as a *large* tarball extraction. (Presumably writing a large file would be similar.) Eclipse, for example, touches a huge amount of files but encryption on the underyling filesystem is not generally noticable. It can be more noticable on a single core, single thread CPU.
If you have a server doing significant continuous I/O, probably benchmarking is the only reasonable way to tell.
Hm, I forgot to mention that it would be for laptop. MSI VR601x, Celeron 1.73 GHz (Single Core), 80 GB SATA, 2GB RAM, CentOS 6.2 x86_64, encryption would be activated by Anaconda on ext4 partitions belonging to LVM Volume Group.
