Specify integer value. For more information, see Specifying Parameter Values.
Selecting an appropriate value for this parameter requires extensive
knowledge of system internals. The value of swchunk should
not be changed from the standard default value.
swchunk defines the chunk size for swap. This value must
be an integer power of two.
Swap space is allocated in "chunks", each containing
swchunk blocks of DEV_BSIZE bytes each. When
the system needs swap space, one swap chunks is obtained from a device
or file system. When that chunk has been used and another is needed, a
new chunk is obtained from a different device or file system, thus
distributing swap use over several devices and/or file systems to
improve system efficiency and minimize monopolization of a given device
by the swap system.
Total swap space is defined by:
swchunk *
maxswapchunks * DEV_BSIZE
where DEV_BSIZE is 1024 bytes.
System-imposed maximum total swap space is approximately 34 Gbytes.
