swapd.conf(5) File Formats Manual swapd.conf(5) NAME swapd.conf - swapd configuration file DESCRIPTION The file swapd.conf is read from swapd(8) at startup. The configuration file is in white space delimited format. An example configuration file might look something like this: minfree 10m maxfree 0 swapsize 32m swapdir /var/tmp maxunusedswaps 5 delay 30 include_cache yes Explanation of configuration elements: minfree Specify the lower boundary of free memory, below this amount of free memory additional swap files are created until atleast thismuch mem- ory is free. This is the same as the -m command line option. maxfree Specify the upper boundary of free memory, above this amount of free memory swap files are deactivated and may be deleted to reclaim disk space. A value of zero (0) is the default and recommended value. This is the same as the -M command line option. swapsize Specify the size of each swap file. This is the same as the -s com- mand line option. swapdir Specify the directory where swap files will be created. This is the same as the -d command line option. maxunusedswaps Specify the number of unused swaps that can exist before swap files start being deleted. This is the same as the -u command line op- tion. include_cache Specifies whether or not to include memory marked as being "Cached" as part of the FREE memory pool. This is generally correct because cached memory is still available for allocation if needed. delay Specifies how often to check the free memory status. The value specified is in seconds. Checking more frequently means swapd can respond to low memory conditions faster, but may also be overzealous in activating swap files if the memory allocations are short lived.
