I'm just really curious how exactly you're measuring that performance hit and what exactly you're doing where you seeing that performance hit? I'm not really sure if you're aware or not, but System Restore isn't working 24/7, it is only activated when you boot up or when you install new programs or drivers.
Yes, I'm quite aware that it's not activated all of the time. The most visible performance hits as you mentioned are at startups/shutdown, installing softwares, drivers and when changing settings, where you can actually count the difference in seconds. Also when I disabled system restore, I managed to free up considerable RAM. IIRC the PF usage reported by Task Manager on my machine was around 95MB+, which was reduced to approx <75MB or so...(I can't recollect the exact figures, it may be more or less). I configure the OS and the applications on my system to be very lean, even though I have an Athlon XP 1600+, 512MB RAM installed, and a 7200rpm HDD. And earlier when I had 256MB RAM and System restore on for a few weeks, there was a discernable "lag" in quite a few things that I did, so as to cause a distraction. You can even feel system restore on things like changing your "desktop properties" settings, etc. In fact it kicks in for nearly all settings that you change, either directly, or indirectly, say thru an application.
For the average AT member, System restore isn't "needed" beause the resources saved can be used to improve over performance and most of the things that cause system failures like installing drivers to upgrading software are much safer in Win XP. For example, you have the facility to roll-back drivers. And modern installers are pretty capable themselves too. XP by itself is a very robust OS. IMHO system restore is meant for users who have a pesky sibling at home who loves to change settings and delete critical files without knowing the consequences or for novices, not for power users who want to maximize the performance of their system.
On systems with 128-192MB RAM, most users will
definitely see a discernable performance increase. Another point to be noted is that most websites that benchmark hardware / software disable system restore before they do any sort of testing for performance reasons, even though most of the test beds feature >1400Mhz CPU's, 256MB+ RAM and 7200rpm HDD's.
