Best practice for tempdb log file I have read many blogs here and there about how to configure tempdb data files but i didnt found any information regarding the tempdb log file.

Here's the strategy that I'm presently using with my tempdb:


I have used the recommendations of Paul Randal on how to split my tempdb data files
I have set the size of my tempdb data files to their maximum and disabled autogrowth. For example, i have 100gb of free disk space and set the size of my 8 tempdb data files to 10gb each. This prevent fragmentation on the disk as recommended by Brent Ozar and also I have 20gb free for my log file.


But like I said, nobody is talking about the tempdb log file. What should I do with it? On my setup, this file is at the same place as the tempdb data files. What is the size and the autogrowth value that I should use with the tempdb log file?
It really depends on how much data is going to flow through the transaction log.  Look at how big the log gets today.  You need to configure the log to be at least that size when SQL starts up.  For most of my clients they end up with a 3-4 Gig transaction log for the tempdb, which contains just a few VLFs and everything works nice and smoothly.
