hi. There is a screen showing the html inside the JSP. The html is to show the category view of shopping mall. Usually, ROPEN html takes 0.2 seconds. But sometimes it takes 5 to 9 seconds. If the Category is selected at html, you said DB would query on related Category ID. This would take much time. I thought ROPEN indicates time that reads static file. If other logics are conducted inside the html, time conducting such logic are supposed to be shown on the SQL of application or socket. I would like to know if ROPEN html is just to read the static file or to include the time conducting logic inside the html.
