Description

This numeric parameter can have any value between 1 and 999999. It indicates the number of hash slots to allocate to detect procedure updates.

The hash table is only used by SirFact to determine if a procedure needs to be recompiled because it or some included procedure has been changed. The procedure update hash table makes it possible to quickly determine that a procedure has not changed without actually scanning the procedure dictionary (an expensive operation).

Each hash cell requires 8 bytes of virtual storage. The default value of 4091 is probably fine for most sites.
