I got to wondering recently if the Vista SuperFetch technologies were really working with me or against me when trying to get my UMPC to perform better.
Undoubtedly the drive in the ASUS R2H isn’t the fastest performing thing around even when it is bursting a lot of data and what my experience of the machine being desperately slow when I closed applications made me wonder if SuperFetch was really working against me.
SuperFetch is supposed to prefetch regularly used pieces of code, beit system code or applications and load them into RAM as RAM is available… ergo unload something and the prefetcher loads something else that may speed up the user response if that application is called upon. (as I understand it).
Given that I increased my R2H from 768Mb to 1280Mb then just maybe SuperFetch is bringing a LOT of stuff into memory each time I close things.
Anyway I disabled SuperFetch entirely by changing..
HKLM\System\CurrentControlSet\Session Manager\Memory Management\PrefetchParameters\EnableSuperfetch
to 0 (from the default of 3).
The only other tuning that I have really is Memory Management\DisablePagingExecutive = 1 to keep all kernel and driver code in memory anyway.
I have found that with my config that performance is generally faster so I am curious if anyone else can verify this with R2Hs running 768Mb instead of 1280Mb and possibly other UMPCs.
Specifically I have found that operations like control panel navigation are much faster – this kind of thing loads and unloads a lot of CPLs (DLLs actually with a standard entry point) and I think that particular option keeps SuperFetch quite busy.
Other info : I did have a ReadyBoost compatible SD card (SanDisk Ultra II 1Gb) running and I am presuming that ReadyBoost is now also disabled since I think only SuperFetch uses ReadyBoost and with SuperFetch disabled the machine goes back to using the XP style prefetcher.
Sunday’s post about the closing CompUSA Vista fire sale racked up some pretty heated comment debates. Clearly, Vista is an emotional subject, which is good reason to ask you, again, to tell us what you think about Windows Vista.
We asked back in December and published comments from readers that had used Windows Vista. But that was way before the official release to everybody.
Nearly three months into Windows Vista’s public release, we ask for your reaction to the operating system. If you’ve used Windows Vista, please tell us what you think of the new software. To spice things up a bit, we’d also like answers to the question: Is Windows Vista Microsoft’s Windows Me II?
The Inquirer has labeled Windows Vista as Windows Me II. I wouldn’t go that far (yet), but I’ll say this: Over dinner last year, I told several Microsoft user interface designers that there were only two versions of Windows I liked less the more I used them: Me and Vista. They were mortally offended, methinks, but that remains my experience still.
The question of Vista as Windows Me II is no small one. Windows Me is kind of a dirty word at Microsoft. Most users clung to Windows 98 rather than go to Me, which may also have deterred consumer upgrades to Windows XP later on. If Vista turns out to be a Me II operating system, then Windows XP could become Windows 98/98 SE II—meaning the operating system people continue to use rather than going to the next version. Heck, Dell brought back XP for new PCs. How telling is that?

Forbes takes a look at Vista, and writes: “More than five years in the making, more than 50 million lines of code. The result? A vista slightly more inspiring than the one over the town dump. The new slogan is: ‘The Wow Starts Now’, and Microsoft touts new features, many filched shamelessly from Apple’s Macintosh. But as with every previous version, there’s no wow here, not even in ironic quotes. Vista is at best mildly annoying and at worst makes you want to rush to Redmond, Wash. and rip somebody’s liver out.” They also look at Office 2007.
