> Currently interval between recaluclation of cahce size is hard coded to 1000
> ms. Resizing/recalculation of cache size is quite expensive method
> (especially getMemoryUsed on MLRUItemStateCache is time consuming)
> Depending on the configuration, we realized that under some load up to 10-15%
> percent of CPU time (profiler metrics) could be spend doing such
> recalculations. It does not seem to be needed to resize cache every second.
> Best this interval should be configurable in external config. file with other
> cache settings (like memory sizes).
