Is there any posibility to write perl script which itself doesn't request more resources thn 10% of system ?

depend on purpose of script, and size of resources available, and whether its cpu or ram or disk you refer to

Purpose: inserting into database huge amount of data
Resources - i don't know machines, it's deend, but i don't like to reach over 5-10% of resources (processor)

Maybe you can give me some clue how achieve this?

you're basically talking about throttling resources being used by a script

How did you decide on 10%, what else is running on the machine? What OS is it running?

if it's on a unix box, you can play with the "nice" and "renice" command, so the process won't get lot's of time on the cpu at once.

PaulTEG: unix/linux based, probably debian or gentoo maybe bsd family - i don't know
So you're right - it's hard to obey limit, i'll try to do it in other way

The one place I've seen this work on Windows is with the Stanford folding project, where the processor is only given over to the folding project according to a sliding scale.

It has to be doable, how though, that's the question.

Is a seperate database box a feasible possibility, they're a lot cheaper than they used to be

What UNIX is it?

On some UNIX's you can do what you want to do; it's not a standard part of UNIX though. In HP-UX for instance you can buy an add-on product which lets you do it - Process Resource Manager which is a chargeable product, though it's included (I think) in some versions of the O/S. I'm sure that other H/W vendors have similar and fine products.
