Editorial Problem: Even the most powerful PC's become non responsive during resource-intensive computations, such as graphic design, media, image rendering and manipulating. The traditional solution has been to upgrade to a faster computer and throw more computing power at the problem to lessen the wait-time. But there's a simple solution that utilizes multiple machines, but without using grid/clustering. For now, this involves a hack, but how hard would it be for an OS vendor to streamline this process?

reniceing a prosess may well just be hideing a problem. for a time distros came with xfree running on a above-avarage nice value to help with responsiveness.

but now with 2.6 the default scheduler monitors the number of times a prosess enters a wait state for more user input and adjusts its priority thereafter. therefor a cpu heavy task will get a bigger priority then tasks like wordprosessors and others that are centerd around user input. these levels will still be maintained so that the current user task gets a slighty bigger priority then a background task tho to maintain a sense of responsiveness.

but like someone else here stated, disk access and the amount of ram available have just as much to say. the moment the os have to start moveing stuff to or from swap is the moment the system crawls to a halt...
