Actually this decrease after 1 hour or 30 minutes. do i need configurate it in web.config or is it a configuration in IIS?
The IIS worker processes continue to grow until they reach an execution time or size limit, and a number of other criteria. They are then recycled with a new process that starts off at the initial memory use. This is by design and permits the application to respond better to multiple similar requests.
These options are described at Configuring Recycling Settings for an Application Pool (IIS 7).
