Replace DeferredCache with LruCache where possible ( #8563 )
...
Most of these uses don't need a full-blown DeferredCache; LruCache is lighter and more appropriate.

Don't apply cache factor to event cache. ( #7578 )
...
This is already correctly done when we instansiate the cache, but wasn't
when it got reloaded (which always happens at least once on startup).

Fix bug where state cache used lots of memory
...
The state cache bases its size on the sum of the size of entries. The
size of the entry is calculated once on insertion, so it is important
that the size of entries does not change.
The DictionaryCache modified the entries size, which caused the state
cache to incorrectly think it was smaller than it actually was.

Speed up cache size calculation
...
Instead of calculating the size of the cache repeatedly, which can take
a long time now that it can use a callback, instead cache the size and
update that on insertion and deletion.
This requires changing the cache descriptors to have two caches, one for
pending deferreds and the other for the actual values. There's no reason
to evict from the pending deferreds as they won't take up any more
memory.
