Dynamic cubes - result set cache

[Cognos8]

Hi,

We are facing perfomance issue in dynamic cube. After applying other solution, trying to find answer for this.In cognos root folder\temp\Result set cache folder is created to have result set cache temp file. When we execute any simple query, the file size increases to 2 gb.

Is there a way to disable this temp file generation ? usually result set cache improves the performance.
Can i disable any other logs  generation ??
