Temp_Db is used whenever temporary tables are created or whenever someone does large sorts. &nbsp;Everytime you restart SQL Server tempdb is recreated, but it doesn't hurt to shrink it once in a while if you don't restart the server that often.<br />

Of course, any time you shrink ANY database, it does have an affect on the server because of the extra IO that's involved.<br />

TempDB database size is usually set base on how much space is needed for processing using temporary table. it seems that your setting is too big. you can decrease your tempdb database from SHRINK database option and set file growth to 10% for tempdb database setting

I want to know what effect it can make to my performance???<br />
Now that temporary tables are used to store in temp_db shrinking it will make it slower? I mean suppose i have shrinked it After shriking it will reduce the speed of temp_db file??<br />
