One of the most obvious bottlenecks in the performance of tempdb is caused by PAGELATCH, in-memory latch contention on the allocation bitmap of each data file used. We can use one of the rules-of-thumb to choose what should be roughly the best number of files, but how then do you check to see whether you've got it right for your data and workload?

If your SQL Server’s tempdb database is heavily used by your application(s), consider locating it on an array of its own (such as RAID 1 or RAID 10). This will allow disk I/O to be more evenly distributed, reducing disk I/O contention issues, and speeding up SQL Server’s overall performance.

select city from t1 order by city;See possible answers
