Question
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?
Solution
This is true in development mode. Enable cache and set http://www.yiiframework.com/doc/api/CDbConnection#schemaCachingDuration-detail
