Cache storage max

[fl]

Why does cache store only 900 items if more than 1000 is stored, and not 1000?

> The cap for cached items is 1,000. If more than 1,000 items are written, the cache stores the 900 items farthest from expiration. This limit might change.

"Batching" the expiry is probably done for performance reasons, similar to how garbage collection works in managed runtimes.

In general - for performance, its a better idea to store a few larger objects in cache than 1000 small objects.
