문제

My test page is processed if believe to trace in 46 ms, while 11 of them I am doing this

 20:53:06.111597 system.db.CDbConnection   Opening DB connection
 20:53:06.118046 system.db.CDbCommand      Querying SQL: SHOW COLUMNS FROM `questions`
 20:53:06.122476 system.db.CDbCommand      Querying SQL: SHOW CREATE TABLE `questions`

Is this obligatory?
