Use_MMAP — use mmap when spooling messages from disk
Use_MMAP = false
Use_MMAP = true
When set to true, Momentum will attempt to memory map message bodies (via
mmap ), rather than allocating memory from the heap and reading the file from disk.
The default for this option is
false. This option should be set dependent on the performance and stability of
mmap on your system.
If you set
compress_spool module will not load. For more information see “compress_spool – Dynamic Spool Compression”
use_mmap is valid in the global scope.
