The larger the original image is the longer it will take, but I would
recommend you do run throe all the images before you release it for the
public, as there will be noticeable slowdown when generating the
thumbnails, I have been working on a site with creates thumbnails of
500x500 images and when you have 30 images to generate, it's like you
are back on a modem.

Do select a good file system, I would recommend jfs, it's usually quite
close to xfs performance, but uses less CPU power. RaiserFS is more CPU
using, but does manage crashes a lot better. Ext2/3 works ok for normal
users. Reiser4 (not yest in default kernels) is still buggy and I don't
recommend the usage of it until it's been at least in two versions of
the official kernel.
