Setting 'System managed' page file for d: drive causes high CPU us

Hello!
Setting 'System managed' page file for my d: drive (EIDE Samsung SP2514N on
JMicron JMB363 PATA and SATA controller on my Asus P5K motherboard) causes
explorer.exe to use about 90% of CPU after a restart for several minutes and
in about 10 minutes intervals during 720p video playback in VLC Player for
several minutes.
RAM 6GB, CPU Intel E6750. Vista Ultimate x64.
I have set 'no page file' for my d: drive (EIDE Samsung SP2514N on my Asus
P5K motherboard) and the problem disappeared. Why does setting page file for
my d: drive cause the high CPU usage? My d: drive is least frequently used.
I have not changed 'System managed' for my G: drive.
I have set 'System managed' for my c: drive (WD5005000AACS ATA) too, and the
problem have not reappeared.
Regards,
Dima

You only need ONE page file for your entire system - you do NOT need one for
each drive......and if these drives are partitions and not
physically-separate hard disks then there's no advantage in moving the page
file from C drive either....

Thanks Gordon for your reply!
I have 3 HDDs: 2 SATA: C: and G: and one EIDE d:. I do not have logical
partitions. MS writes that Windows uses a page file on a less busy HDD at a
time. The busyness changes over time, therefore MS recomends to spread a page
file over all phisical HDDs.
What program can assess performance with different locations of a page file?
I want to compare different locations of a page file.

Never heard that one before - can you post a link to that?

Thanks.
i suggest then that you create a very small page file on C for the memory
dumps and create a partition on your least-utilised HDD purely dedicated to
the second, windows-managed pagefile.
(The article only mentioned TWO page files as above, not one on each
drive....)

Thanks Gordon for your suggestion!
My least-utilised HDD is EIDE Samsung SP2514N on JMicron JMB363 PATA and
SATA controller on my Asus P5K motherboard. Asus writes that EIDE controller
works slower than SATA on Asus P5K motherboard. It looks like explorer.exe
loads CPU more when a page file is on EIDE HDD.
A least-utilised HDD changes over time: uTorrent seeds several-Gb-files and
I play HD videos from C:, D: and G: HDDs alternately.
If D: and G: HDDs are busy at the same time, its better to use a page file
on C: HDD, therefore the C: page file should be normal sized. If only G: HDD
is busy, its better to use a page file on d: HDD, because C: is a system HDD.
Am I right?
How to test performance of different page file locations?

Trial and error?

Thanks Gordon for replying!
Is there a software that evaluates PC performance including a page file usage?
Why could explorer.exe use 95% of CPU time for minutes without a user input?

I don't know. Have you tried googling "PC performance analysis software"?
