WebThis is mainly useful when maintaining a cache of objects which can be regenerated, but only through a cpu intensive process. it's generally useful to keep such objects around in a cache, in case they are needed again, but for memory reasons, long running processes will generally want to free unused objects up after a time. WebThe `lowmem_reserve_ratio' tunable determines how aggressive the kernel is in defending these lower zones. If you have a machine which uses highmem or ISA DMA and your applications are using mlock (), or if you are running with no swap then you probably should change the lowmem_reserve_ratio setting. The lowmem_reserve_ratio is an array.
