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

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....

Setting 'System managed' page file for d: drive causes high CP
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. Regards, Dima "Gordon" wrote: "Dima" wrote in message ... Hello!

Setting 'System managed' page file for d: drive causes high CP
"Dima" wrote in message ... http://support.microsoft.com/kb/314482 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?

Setting 'System managed' page file for d: drive causes high CP
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? Regards, Dima "Gordon" wrote: "Dima" wrote in message ... How to test performance of different page file locations? Trial and error?
