is this service necessary?

IKE and AuthIP IPsec Keying Modules a reall necessary service to have enabled just wanted to knoe cuz i like my computer running lite.....

 

Disabling random services will not speed up your computer, and tweaking in Vista i mainly a myth.

About your service - IP sounds like Network/Internet relatted to me.

If your computer is running slow or sluggish at good/decent specs try to determine the caue using the sysinternals tools.

 

So just let it be?

 

Do not disable those services. It is important I think.
Vista would run slight I guess 0.5% faster if you disable many of those services.
START-UP thingy lesser would be faster(this is true only).

 

well just wanted to know if it was a necessary task and by the looks of it yes ill leave it on then...............thx for the help

 

I only disable services related to other programs, like for example, Acronist True Image Scheduler.

One very important service i disable on the spot and immediately notoice a big difference in performance is the Machine Debug Manager, which is related to Microsoft Office's programming module for debugging, this is a useless service only good for programmers, but I wonder how come its enabled for all users and causes your system to behave weird and big decreease in performance.

Rest of, leave the "Windows" services alone

 

I love it when people make up figures.You don't know that it would be 0.5%

Disabling the services would offer negligible performance gain so leave them is what you should of said.

 

I know a guy, who knows a guy, who knows a guy who says disabling that service will make your system perform .06732 percent faster!

 

I know someone says otherwise!

 

The only services I always disable are SSDP Discovery service (which from XP days has always been dangerous to leave running) and I also disable superfetch, that is pretty much it I leave everything else alone.

 

Disabling Superfetch is wrong...

It increases performance.

 

SSDP works quite fine on vista and shouldn't be dangerous anymore. Disabling Superfetch makes your system slower and less responsive, espencially while booting.

IF superfetch slows down, you have to kill all prefetchdata (C:\Windows\Prefetch), and restart superfetch then (first stop, then delete, then start again) to reset it.

I hoped for some superfetch gui in win7 to make it more simple.

 

well what i saw about disabling superfetch its that once that service was disabled i saw that ram wasn't being used so intelligently by that i mean i closed a program and my ram wasn't given back so........ was the other programs i closed them and ram was still being utilized as if the program was still open weird huh it does improve performance i think that day i disabled that service is the only time my ram reached 97% utilized.....

 

ram shouldn't be given back if you close a program. maybe you notice "oh i should open it again, i forgot something" and then it's still in ram?

 

well lets say u open firefox and task manager under task manager firefox is open and utilizing 130,250mb close the program and boom the ram is given back....i dont understand what your saying exactly.....

 

i'm irritated myself at the moment

but all in all, superfetch should enhance your experience. try it?

 

yeah i did it runs much smoother and more responsive than when it was disabled

 

and that's what counts. don't look at the taskmanager to see the "ram usage". because you want all ram to be used by the os. the os should know best on how to use it effectively, and most often, it does

 

I can explain that RAM usage by Superfetch, it's simple...

Superfetch is meant to fill your RAM, that's what it's there for. While that may seem like a bad thing at first, it is actually good because it means you make use of RAM that would otherwise not be used for anything. Superfetch will analyze your computing habits and, based on that, fill an amount of the otherwise empty part of your RAM with data which it guesses you will be about to open next.

So if, let's say, you're using your favorite music application every evening on the weekend, after some time Superfetch should notice that this is a regular occurrence and therefore load files which are needed for that particular music application into RAM shortly before it expects you to start that music application - on the weekend, in the evening. This would result in a faster startup time of the application, because it's much faster to load data from the RAM than is loading them from an HDD. And faster application startup times can greatly increase the subjective speed of your computer - one of the reasons why SSDs are an incredible performance upgrade today, by the way.

Whenever you need more RAM and there's data in RAM which was put there by Superfetch, Windows will drop that data immediately. All this enables you to make full use of your RAM whenever it wouldn't be used otherwise. So while it seems that you have much less RAM available, you don't - maybe a very tiny amount which Superfetch itself needs to operate, but that's it.

There have been tests that have not been able to reproduce a speed gain by using Superfetch.
There are users who report that Superfetch helps a lot, while there are others who report that it did not give them any speed increase. It is, however, not a problem to leave it enabled regarding RAM usage if you're uncertain whether it helps or not. And you can of course still simply disable it, wait some days or weeks and then re-enable it to see if you notice any difference. True speed increases are often only noticed by many as soon as people have to go back.


Superfetch only helps if you're using HDDs, not if you're using SSDs. It is highly recommended to turn off defragmentation, Superfetch, Prefetch (boot- as well as application optimization) and Readyboost completely if you use an SSD. However, this is only true for good SSDs with high IOPS values.
Windows 7 will handle that automatically.

 

I'm really, really curious about this strange fetish some people have with wanting to maximize the amount of unused RAM they have on their systems. Can anyone tell me what the point is of disabling something like superfetch just so that one can have heaps of idle, unused RAM lying around?

With all due respect, that's like buying an exotic supercar and then using it exclusively to drive down to the end of the driveway and back to pick up your morning newspaper.

The fact of the matter is, superfetch does not take RAM away from the system - nanoseconds after you fire up an app that needs RAM that's been prepopulated by superfetch - *>BAM<* - that RAM is handed over to that new app without a second thought.

Seriously, disabling superfetch is what my old granny used to call penny-wise, pound-foolish - for the false illusion of a quicker startup, you get rid of a whole lot of faster system operation long after startup is a fading memory.

EDIT: Just to respond quickly to one point made by Christoph.krn - given that superfetch is designed to prepopulate RAM based on prior usage patterns, it's entirely possible that certain users who do not have an easily determinable usage pattern will not experience much if any gains from using superfetch; on the other hand, they are unlikely to experience any negatives from superfetch, either. On the issue of SSDs, I'll defer completely as I have no experience or larnin' about them things (yet ).

 

This method is just like installing an OS to the RAM.
An OS that boot at RAM is a lot faster than HDD.

Anyway, Superfetch is good or bad to disable it?

 

There are two separate mechanisms, Prefetch (which was already used in XP, and is being used in Vista as well) and Superfetch. Unlike Prefetch, Superfetch DOES indeed analyze the user's behavior. That's why it often needs some time for it to show its full potential. It's meant to come by the degradation of Windows due to fragmentation on the disc and more and more installed software (which can have various side effects, like explorer getting slower and slower).

There's no need to disable it, but you can try it to see the difference. If you want to do so, it's safe to disable it.

 

unused ram is wasted ram

 

Wow what a response to my post about turning off superfetch . Anyway I have my reasons for turning it off, because as shyster pointed out some people's user pattern is hard to determine so I found that superfetch was trying too hard to "learn" me and was not succeeding.

When ever I turn on my notebook I hardly do the same things therefore the constant disk thrashing as superfetch was trying to page stuff into memory was starting to get on my nerves so I disabled it and it has been working out fine now for over a year. I keep fragmentation low (below 3%) and my programs launch very fast even without superfetch. As long as you keep readyboost enabled then you will have no problems with boot speed as readyboost enables readyboot which will significantly speed up boot time.

 

well everyone has their own opinion about what services to turn off and which to leave on ................. its a matter of user preference

 

Not quite - especially Vista.

You should leave all services running in Vista - excep those that you added yourself.

Reason:
Unless you programmed the OS you do not know how services interact and how they affect the system.

 

thats true i disabled a couple services and sometimes my internet didn't work or my printer and so on but i always make restore points so no worries....

 

Pen an paper Write down every change - but its eventually useless - the difference you'll get is very small.

 

its small but my pc boots up much faster than when i bought all that bloatware...................

 

Services aren't bloatware.

And yes, things like google Picasa (who needs that?) adobe quickstart, java update sheduler (does that have to start every time you start your computr? It launches when you start Javaanyway, same for Quicktime) are bloatware and do impact startup performance.

But they aren't services.

 

i knoe but if u notice if u install itunes it also adds services like ipod service,,, bonjour service arent those services, they are under services............. i just find those thing to be bloat just IMO

 

Services do impact boot up time as well. Never touch any default services that you are not absolutely certain about. Third-party services are most times safe do disable without getting unpredictable problems. But write down the changes you make or make a backup of the services list. Be aware that after booting, most services hardly impact anything except if that's what their main purpose is (like a backup service that spins your disc, for example).

If you're unsure, you can also try setting services to "Automatic (delayed start)" instead of "Disabled" to improve boot performance.

Ideally, you would get a harddisk with lower random access times or a good SSD.


The iPod service helps identifying an iPod that is being connected to the computer. I guess this is to start up iTunes in case if it's not running when you connect an iPod or maybe to make the synchronization more stable.
Bonjour is a technology by Apple that enables computers and other devices to see each other via network hassle-free. iTunes uses this to share music via network.

 

That's a little different than the services that are built into the OS. Disabling pointless third-party services that you installed yourself (whether you intended to or not) is not the same thing as disabling a service that Microsoft wrote into _Vista.
