Documentation
Definition
A foreground write is activated when when a user thread cannot locate an empty or unmodified buffer in the shared memory pool, therefore pages must be flushed in order to make space. Foreground writes should be avoided. If foreground writes are occuring, tune the value of the page cleaning parameter by either increasing the number of page cleaners or decreasing the value of LRU_MAX_DIRTY.
