gpgslo

Description

When the vhand daemon (page handler) executes, it won't start stealing back pages unless there are fewer than gpgslo free pages in the system. Once vhand starts stealing pages, it continues until there are gpgshi pages.

This parameter is specified in /var/sysgen/mtune. For more information, see the gpgshi and gpgsmsk kernel parameters.

Value

Default: 0 (automatically configured to half of gpgshi if set to 0)

Range: 10 pages - 1/2 of memory

When to Change

This value is adequate for most systems.

Notes

If this parameter is too small, vhand does not start swapping pages; thus entire processes must be swapped. If this parameter is too large, vhand swaps pages unnecessarily.
