Does anyone have any formulas for tuning the dbcachesize (memory cache for
indexes) and cachesize (memory cache for elements)? What are the best
statistics to look at to know if these need to grow? It is my understanding
that "cachesize" is actually the number of objects to cache in memory and not a
Kb number, since object can vary greatly in size this seems like a real hard
one to manage.
