Wondering what the setting should be for a paging file? Does it effect speed of computer? :thumbsup:

Hello,

The settings of the page file depend on the ammount of RAM available and also hard disk space. The minimum allowed is 2MBs and the max (on most XP systems) is 4096MBs. Traditionally a setting the value to one and a half times that of the available RAM is enough.

Many people will say that altering the page file will not produce any performance gains. To see any real performane gains would depend on the hardware being used.
Regards,

Alan.

The only real gain on modern systems is to set the initial and max sizes to the same value.

But PageFile performance gains are nill unless you are constantly running out of ram.

If you are maxing out your Page File size, or are getting notifications in Windows that you are running low on Virtual Memory, you may have a problem with one of the following:

:: You are maxing out your RAM putting excess information into your Paging File -> upgrade your RAM
:: You have multiple programs running in the background -> possible malware infection opening up excess services or programs which are depleting your available system RAM
:: You have multiple program windows open, more than your RAM can handle putting excess information into your Paging File -> close some windows, possibly upgrade your RAM

The only method to really increase speed on your machine is to upgrade your CPU, the bus and bus speed on your motherboard. Increasing RAM will help you take advantage of multiprocessing which is your machine's ability to process and work between multiple programs and services simultaneously. Although at any given time, there is only one process or program that is running, your CPU processor speed is rated in hertz (Hz) which is the number of cycles per second your processor is running. Because most processors nowadays are rated in MHz or GHz, this means that your CPU can run millions or billions of cycles (or processes) per second. Therefore, if you have an Intel Centrino processor rated at 1600 MHz (1.6 GHz), it can run 1 billion 600 million cycles in a given second - lightning fast so that it appears as if all programs you have running are being processed simultaneously.

You can read more on microprocessor speeds here:

I've recently listened to an interesting presentation by David Solomon about Windows Memory Management (pre-Vista) and he states that there is no relationship between RAM size and pagefile size (with the exception of saving dump files).

So, as a lower limit, the pagefile should be at least the size of your physical RAM (to effectively save memory dumps). To effectively monitor the largest size, I'd suggest that you monitor pagefile activity in Task Manager...Performance tab to see what's being used.

I'm waiting for the free time to review the presentation - but it's 1 1/2 hours long and has a bunch of other stuff that I'd like to get out of it. So I dunno when/if I'll be able to post back here.

If you're interested, here's the link to the presentation: http://www.microsoft.com/emea/spotlight/se...001491050E0E6C3

I always like questions about computer "speed"...since such are often quite nebulous and the reality is that speed increases in computers cannot often be perceived by common home users.

As for the pagefile...I've tried various locations and sizes, just for the heck of it...and came away convinced that the users like me should just allow XP to manage it's size and location. That seems to work seamlessly for me.

Tweakers do things just for the sake of it...I understand that nanoseconds mean more to them because they choose to make it more meaningful in their quest to squeeze "optimum performance" from a system they (presumably) are taking very good care of. Doing this is a way of life for them and it doesn't matter how truly meaningless the performance tweak might be...those nanoseconds and clock rates matter to them :thumbsup:.

Well, the average person inquiring about speeding up her/his system...probably isn't even doing basic maintenance/protection on the system, yet wants to optimize speed.

A contradiction, if you ask me.

I've lived without a pagefile, and I've lived with one. These days I put my pagefile on a separate hard drive and it seems to help speed things up a bit. But it prevents me from saving dump files - so what's a fella to do? :thumbsup:
