Page Faults Windows Task Manager
A page fault (I have 190,000,000 of them in 10 minutes) seems to be when the code being executed attempts to read or execute past the "currently loaded memory frame" and Some softwares (aS video editing ones)need the pagefile, and if not there u may expect lots of crashes even if u have 10GB of ram! There is an Interrupt Service Routine that gains control at this point and determines that the address is valid, but that the page is not resident. If it is in the cache, because it's a memory-to-memory transfer, the program still gets it quickly. check over here

But reading some of the links provided here doesn't seem to make me think adding memory will help. slide 6 of 6 Update for Windows 8 This update is provided by Ryan Tetzlaff. Is there a better way to look at page faults? The easiest way to stop faulting from occuring so much is to have more RAM.
That might be what you saw, because you seem to have ample free memory. –Ron Feb 1 '11 at 21:27 1 There are memory caches at different places (processor, motherboard, If you're paging out, the number is VERY high. I decided that I didn't want a swap file on the C: drive at all, but I didn't mind Windows handling the swap file automatically on the other drive. Hard Page Faults Fix This is called a "soft page fault." The thing to bear in mind is that this transfer is very fast- much faster than reading the content from the hard drive- so

- Of course, if Windows runs out of swap space in a fixed-sized file, it may promptly crash.
- I would consider any sustained number of hard faults to be indicative of a memory shortage.
- It is imperative that hard page faults are resolved in a timely fashion so that the process of resolving the fault does not unnecessarily delay the programâ€™s execution.
- So I guess its normal. __________________ :₪(¦[Ðєςąץєd.ςєłł]¦)₪:™ AV-710 Mod | 500W Super Flower Black Diamond SF-500P14 Review Know what's bang for buck?
- So I unselected "Automatically manage paging file size for all drives" and then clicked the C: drive.
- Here Windows will make recommendations as to the size of your page file.
- We have three servers having performance issues.
- The server from my original post however reports 376MB of available memory and a % committed bytes in use at 28% in perfmon.
- You could also try moving your swap file (pagefile.sys) to another internal hard drive (not to another partition on the same hard drive).

Pretty conclusive proof could be gathered by installing extra RAM and seeing if the problem goes away. Now that I'm starting to see it on more servers though I'm not sure if I'm missing something else I should be checking, like other Performance Counters or something to try Memory Page Faults/sec So to summarise i think that XP is purely trying to optimise RAM and virtual memory usage, even though you are sitting there doing nothing...

To get a picture here, look at Physical Disk: Avg. A page fault occurs when a program requests an address on a page that is not in the current set of memory resident pages. http://davegaubatz.com/page-fault/page-faults-task-manager.html Having said how many page faults I have, it seems that windows is NOT reading them from hard drive (my hard drive is not ALL THAT fast ;-).

However, if this number only spikes during hard page faults, you have a problem with memory capacity and not disk performance.
I'd have thought, at least for W2K8 R2 that this counter would be exposed directly in perfmon. Disabled that, the page fault total went down to 3,000 / second, and everything runs great. –David Robison Feb 4 '11 at 21:03 add a comment| 3 Answers 3 active oldest My only correction available is to kill explorer.exe in the task manager and restart it (so that I'll have my desktop gui back).

If it is not affecting performance, i would not worry bout it 2 much. i.e. If you want to manually control your page file you can click the change button. have a peek at these guys I remember that I was going to restore the Swap File after doing a data restore and defrag - but now I realize that I forgot!!!

Cache faults are resolved by reading the appropriate file data from disk, or in the case of a remotely stored file â€“ accessing it across the network. windows-server-2008 performance-monitoring virtual-memory share|improve this question edited May 24 '11 at 14:48 asked May 24 '11 at 14:18 MattUebel 4873927 add a comment| 2 Answers 2 active oldest votes up vote There is still a performance difference between memory and a SSD drive, but will generally not be noticeable to you.
