This is our database (MSSQL20012 Standart) cpus and tempdb configuration. What dou think about tempdb configuration? We have to performance problem some times.
As per blog https://cloudblogs.microsoft.com/dynamics365/no-audience/2015/09/25/ax-performance-analyzing-key-sql-server-configuration-and-database-settings/?source=axsupport it is recommended to have 1 file per processor, but with that many cores 8 file should be ok.
Thank you for reply,
I understood our temp files count ok, but we must change autogrowth value. I will try it.
Splitting TempDB is one of item in the performance improving.
apart from that you have to make sure that related Trace Flags are enabled other wise it wont give you result what you expecting .
when you split TempDB you need to enable 1117 and 1118 trace flags respectively.
apart from that just try to use High performance Volume /Disk Tier for TempDB. Keep Total TembDB size at least 25% of Transactional Database.
Hope this will help.
Thanks & Regards,
The configuration depends on many other factors such as: number of cpu cores, ax database size, tempdb contention, tempdb usage, how often it outgrows(which should be avoided) etc.
Beside that performance of the DISKS (IOPS/ Latency / Bandwidth) where TempDB is placed has a big impact in overall performance of the application.
I would suggest first narrow down the business process having performance issues and their time stamps and then work further with DBA or involve implementation partner.
