John McCormack takes a look at dbatools with an eye on performance tuning:
DBATools is well known in the SQL Server community for the ease at which it allows you to automate certain tasks but did you know that DBATools can help with performance tuning your SQL Server. As my job recently changed to have more of a performance tilt, I wanted to investigate which commands would be useful in helping me with performance tuning. It turned out there are quite a few.
There are some good commands in here.
