Use text matchers for all incoming connections to ensure a faster response time. Text matchers take approximately one microsecond per request.
Minimize the use of syntax matchers. Syntax matchers parse SQL request that Dynamic Data Masking listener port receives. A syntax matcher can take over 100 microseconds to process.
Configure the matcher to keep the matcher result valid for all concurrent SQL requests that are open in a session. The default time that the Rule Engine stores matcher results is 3,600 seconds.
