dynamic_pager [-E] [-F
layoff_ point] [-P
Manages virtual memory swap files. This tool is started from /etc/rc during the boot process.
Starting with Panther, when dynamic_pager is invoked without -H, -L, or -S options, it creates swap files that are sized dynamically according to paging needs and available disk space.
Encrypt the swap file.
Specify the base absolute pathname for swap files. Swap filenames consist of this base and a whole number suffix, starting at 0. The default is /private/var/vm/swapfile.
Create an additional swap file when free swap space drops below the
hire_point in bytes. The default is 0, which disables the use of this swap space.
Attempt to consolidate memory and remove a swap file when free swap space rises above the
layoff_point in bytes. The
layoff_point must be set higher than the sum of the swap file size and the
hire_point, unless it is set to 0 (the default), which disables layoffs.
Determine the priority of this swap space. The default is 0.
Determine the size of swap files created, in bytes. The default is 20000000.
