Hi,

the script example looks very basic. Hard to believe this can not be compacted in several ways. Maybe you show us the real script, so there is a better idea of what you are doing.

Thought's so far

If you're on a multi-user-system it may be not such a good idea to parallel i/o-heavy processes because you may completely eat up the available i/o of your machine and cause extreme loads at within your server. This could slow down the whole server very greatly. I would suggest you keep the i/o tasks sequentially.

The "ln"-commands may be executed sequentially too, because they should be so fast, it should be a duration that is hardly noticed to create some thousand symlinks / hardlinks. (1000 Links in one second on my 10 year old desktop machine).

As I can see from your small snippet, cpu-power is not required here at all, but only raw i/o so you will not profit from parallel executing your script.
