sys_regcache

Description
Regular expression searches require a compilation procedure to be performed before the actual search. In order to speedup handling of expressions, a number of compiled expressions are saved in a cache pool: this parameter specifies the size of this pool. Note that setting this parameter has the effect of clearing the cache (even if the pool size if kept unchanged).
