Hey guys,
My Lumia 640 was running slow on Windows 10. It seemed like my apps were always closing and taking forever to reload.
The default page file settings regardless of the amount RAM in the phone is locked at 256MB. Where the persistent storage is also flash memory, writing to the page file shouldn't cause any major slowdowns.
I used interop tools and the data located at https://msdn.microsoft.com/en-us/library/ms912851(v=winembedded.5).aspx to set the minimum size to 128MB and the maximum size of the page file to 768MB. The results were immediate!
Thinking it was a fluke, I rebooted my phone, and I noticed that it starts much faster now, too! As always, ymmv, but post your results in this thread if it helps!
Additional Info:
1. Setting the location of the page file to anything other than "u:\pagefile.sys" will cause storage sense to display a virtual memory size of 0 MB. To verify that your change worked, enable MTP Root Access in Interop Tools, plug your phone into a pc, and then navigate to the location of the new page file and verify that it was created.
2. Don't set the max size of the page file to be larger than the amount of free space available in the "apps and games" area of the phone. Setting the max limit too close to the amount of free space will cause crashes as the apps will lose "breathing room".
Edit 2:
After playing with this for a while, I discovered that the phone prefers a static page file. The settings that gave me consistently good results without crashing was to move the pagefile to the system partition (c:\pagefile.sys) and to lock it at 512 512. I am on rs1.
There appears to be an rs1 bug that if the memory usage goes beyond a certain number, the phone will become unstable. This is unrelated to the page file adjustment. How do I know? My brand new Alcatel IDOL 4S with Windows 10 gets wonky if I open too many apps. It has 4GB or RAM that is OS limited to 3.5 GB.
