Windows Microsoft's Professional Developers Conference is currently under way, and as usual, the technical fellows at Microsoft gave speeches about the deep architecture of Windows - in this case, Windows 7 of course. As it turns out, quite some seriously impressive changes have been made to the very core of Windows - all without breaking a single application. Thanks to BetaNews for summarising this technical talk so well.

We have enough memory in today computers that swapping is mostly unneeded. If you have more than 1GiB of memory and you do a fair use of your computer, you'll see most of the time the swap isn't needed at all. I have 1GiB and my KDE desktop uses no more than half most of the time with browser, mail client, chat client and torrent client. Any program that's using more than that is probably misbehaving and ought to be terminated. When you have swap, say double your RAM, and a program goes rogue, it will start consuming all available memory, and then the kernel will allocate all available swap to it. That's gigabytes of swapping until the OOM kicks in, producing a lot of disk thrashing and the normal slowdown. The disk IO is producing the feeling that you need a new computer. Hopefully, in a few years swap will be totally unnecessary.

I doubt it will become unnecessary. We will need a fair paradigm shift, before that occurs, I think. Having more memory begets uses of more memory.

However, for general use cases, more RAM and no swap works great, on both Windows and Linux. Any process that can try to use up all my RAM deserves to be forcefully killed ;) .
