Config.trim on minimize
Contents
Background
On Windows operating systems, when a program is minimized and left for a period of time, Windows will swap memory the program is using from RAM onto the hard disk in anticipation that other programs might need RAM. Because of the way Mozilla applications are stored in memory, Windows is much more aggressive in swapping out the memory they use, which can cause a delay when the program is restored. This preference determines whether to mark memory as preferably swappable, from a minimized Mozilla Windows application.
Possible values and their effects
true
Allow Windows to swap out memory when the program is minimized.
false
Prevent Windows from swapping out memory when the program is minimized. (Default)
Caveats
This preference does not exist by default.
Recommended settings
Any positive effect of this setting is dubious, since any memory saving may be illusory.Bug 420267, comment 7
However, if you're experiencing problems with the application consuming too much RAM (Mem Usage in the Windows Task Manager), you can try setting this preference to true. If you're not experiencing any problems, it should be left at false to maintain application responsiveness.
