tempdb initial size

  • What would cause the initial size of my tempdb to be 32gb on boot?

  • What is the size of model database? Also check if there are any procedures running with hash table being called.

  • Two instances 16gb and 6gb

  • By default, initial size of tempdb after restarting is 8 MB. However, if its size is set to different value, the initial size of tempdb after restarting will be the set value.

    The value in the model database is the initial size while creating a new user database. It has no effect on the initial size of the tempdb, if someone changes it, after restarting.

     

  • I concur with SQL_Oracle above. That's been the way I've always seen it work.
