Notes to Callers We recommend that you set thematchTimeoutparameter to an appropriate value, such as two seconds. If you disable time-outs by specifyingInfiniteMatchTimeout, the regular expression engine offers slightly better performance. However, you should disable time-outs only under the follow...
