I have an application in asp.net with Oracle database 11g. In Database every day approx. 40000 records has been added.
Site has been published on IIS server 7.0. On Day start site works normal. Database showing poor performance. But after actively using site for 3 to 4 hours it slows down. Daily active users are approx 15. Provide solution to increase performance of database or application. Also provide tips to avoid common mistakes which harms application performance. No extra settings has been configured in Web.config file, IIS Server and Oracle Database.
