I have set the <WorkingSetMinimum> property to 2.4GB in my reportserver 2008 config file.
By defintion, <WorkingSetMinimum> setting means,
- Lower limit of service memory consumption; memory will not be released if the consumption is below this amount, though the service will not reserve the designated amount of memory when it starts.
- If service uses more than the designated amout of memory, it will release back the memory only till this declared value and not beyond that, which means it should keep 2.4GB as designated.
