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.

I can set the size of the virtual memory page file in windows, or leave it to the default setting. Why can't I also tune this behavior that is essentially controlling similar behavior?

The pagefile size has no effect unless it is set to be too small. The OS will not use the pagefile to store information that could just as well be stored in memory (old modified pages do eventually get written out, but they won't be discarded and read back in unless there's other demand for memory).

Edit: I'm tired, I didn't understand that I had posted the previous message

Response:
Yeah, obviously the page file setting only comes into play when windows would like to allocate more memory (for cache) than you have. It used to grow the page file by loading things from the harddisk into memory ( which was the page file, located ... on the same stupid slow hard disk). Read on for why I used to set this to be pretty small.



Additional page file Comment:

But I can set the size of the virtual memory pagefile. I used to have to do this on weaker systems to prevent them from running out of space while the computer was running.

I'd rather have the option to control it. My memory uses are non-conventional, I understand why they did it this way. If you gave me a choice, I'd prefer to have the option. The fact that you have to explain this over and over again to everyone. you could have avoided all of that with just an option. Let people play with it and discover how awesome windows engineers were in their wonderful default setting! Sometimes people need to see the before picture, in order to comprehend the beauty of the after.
