Windows 7: WHAT IS STANDARD STARTUP TYPE FOR 'SuperFetch' SERVICE?

WHAT IS STANDARD STARTUP TYPE FOR 'SuperFetch' SERVICE?

ON MY PC WINDOWS7 64bit SSD; Superfetch is set to 'manual'. It can be set to either manual, automatic, automatic (delayed start) or disabled. Can someone please tell me what is the standard setting for this service???

Also noticed that as I leave my PC running 24/7 when I get up in the morning the RAM percentage seems to creep up to about 50% max. I alway switch off Firefox before bed as I know it has RAM leakage problems with the current version 13.0.1 But even with it off my RAM can creep up after extended period of inactivity.

Can someone tell me if this is normal and whether or not SuperFetch flushes out RAM when a new program is initialised that will need the RAM as a priority.

Thanking you...Gary

Apparently some other app you've got has a memory leak. You'll have to test that app by app.

Thanks for your information re SuperFetch...have switched it from Manual to Automatic. Is the 50% RAM usuage figure I get after computer is left on overnight possibly just SuperFetch doing its job? I have 8GB of RAM and do you know if when an intense RAM usuage program starts will SuperFetch simply flush out the RAM cache or will I get a crash/freeze situation?
Have checked Windows Task Mgr>Performance>Resource Monitor for running programs and the only one which creaps up steadily is Firefox but I turn it off at nite when not needed. Other programs vary up/down or remain static but not increasing steadily over time like Firefox does.

Thanks ... Gary

I can't really say for sure. But w7 seems to manage memory pretty well. I've got the same amount installed and often get to 50% or a little higher (but I typically reboot only once or two times a month). I also unload (close) browser pages that are connected to internet sites, because you never know what kind of junk on there continues sucking up memory just because the page is loaded (I'm sure you've noticed that before -- you'll see usage go up and up, close the page and it drops to where it was before). I usually leave the browser running though, with two tabs open on internal pages.

But just because you see it rise to 50% doesn't mean you couldn't get by with only 4GB. w7 is going to allow use of the memory that's available to it, swapping to/from page file as it sees fit. And to be honest, I've not had any problems with the way it manages it.

Thanx for the info and help.

Was confused by SuperFetch within services being set to manual rather than automatic as the way it works implies that it is an automatic service. One forum I checked out stated that as I have a very fast Intel SSD that windows may have switched SuperFetch to manual as it's original design called prefetch on XP was intended to speed things up a tad when using standard platter HD.

Am getting the impression that maybe I do not have a problem at all and is just this service doing what it is supposed to do. I use very much the same 4-5 programs daily and it has learnt what these are. Glad you mentioned that RAM usuage in the 40-50% range is not problem. Also other forums have mentioned that the RAM cache filled up by SuperFetch will flush as more demanding programs are opened. Once such programs are not making such a demand it will repopulate cache with data of most used programs.

Thanks again... Gary

You're quite welcome!

Trying to learn how well w7 handles memory is almost comical as the whole time you're observing its activity it's doing its own learning and changing its behavior! Really started with NT though, it's just doing a lot better these days.
