Maybe I’m old school, but do you ever feel like optimizing SQL is like playing a video game?
Keep on shooting, hopefully you don’t hit your thrusters and drift and then die!
Does your SQL DBA Team (or did you):
NTFS Allocation Unit set to 64KB for the SQL Server drives
Dedicate memory for the OS (set SQL to use max memory)
Set autogrow to be greater than 1 MB?
MaxDOP (degrees of parallelism)
TempDB’s are on separate mounts (and match the number of cores)
Database and log files are on separate mounts
Backup SQL Server encryption keys
