That hardly compares to the 'cat' being run here, untuned and untunable. You're doubling the amount of work done for a <1% improvement in speed -- and with 30,000 concurrent processes, that's time something else probably could've used.

On a single core system running ancient unix it was very important to minimise the number of concurrent processes. This is really not the case nowadays unless you happen to be running unix on a home system.
In my early shell-scripting days I wrote scripts that I'm sure would need your 36 processors to function with any efficiency Smilie Having CPU power to waste hardly makes it a good idea to do so.
