XP pagefile on flash memory

[rsegoly]

Hi,

I have Samsung Q1 UMPC, it has 512MB RAM only, and I will try to
upgrade (its not straight forward process), I know one of the ways to
improve memory handling and startup speed, is by defining static fixed
size page file and placing it on fast memory as external flash memory.

I have 4GB CF attached to the device, but can't succeed in moving the
page file to it, although I disabled the paging on C and defined it to
D only.

Any good advices?

I don't think xp allows for that. And even then, it is not designed for
it (vista comes with the readyboost feature). Your harddrive is much
faster in sequential reads

You can not put your page file on a removeable drive.

In this case, the egg must come before the chicken. XP is already
attempting to implement the swapfile before it implements the driver for USB
and so forth for the removable flash drive. Its a bit more complicated than
that, but that's it in a nutshell.

What you know is wrong. Dynamic pagefile is preferred and you can't put a
page file on a removable drive. Even if you could put the page file on a
memory stick, it would slow down your computer to intolerable levels.

OK, I understand

He is wrong for XP, but you can do it in Vista.

It's called Ready Boost

This is an interesting article....

Well actually, readyboost doesn't replace the pagefile, it justs act's as a
supplemental cache. I doubt you could get rid of a local pagefile for
windows.

Hear are some performance comparisons using readyboost.

You will see you are far better of shelling out a few extra dollars for 1 GB
RAM under Vista than messing about with flash drives.

ReadyBoost is not a replacement for the pagefile. Even if you are using
ReadyBoost you still cannot eliminate the pagefile and you cannot put
the "real" pagefile on a USB stick.

Very quickly said and without going into the nitty gritty of the Windows
Memory Manager the pagefile is a cache of items moved out of RAM and
ReadyBoost is a cache of the pagefile, or more specifically it is a
cache of portions of the pagefile. There is absolutely nothing that is
not in the pagefile that is on the USB stick. Anything needing to be
moved (cached) out of RAM is not moved to ReadyBoost or the USB stick,
it is moved to the pagefile. ReadyBoost is then used as a disk cache of
sorts for the pagefile or for portions of the pagefile. If the Memory
Manager later needs to fetch the paged memory pages it will get it from
the faster of the the two caches, random reads are faster on flash
drives but sequential reads are faster on hard disks.

So the bootom line is that even with Vista you still cannot move the
pagefile to a USB stick, Windows will not permit it.

Like hell. No hard disk average performance can come anywhere near
semiconductor memory time performance. Mere rotational latency
precludes it. Longevity is a different issue however.

You really need to explain why faster media would be slower.

USB interface?

Try and read up about it. How fast can those flash drives transfer? They
don't even get close to your harddrive. Only in random seeks can they
outperform the harddrive
