Starting with SQL Server 2022, transaction log file growth events up to 64 MB in size can benefit from instant file initialization (IFI). As usual, the transaction log is otherwise unable to benefit from instant file initialization.
This should be a big performance improvement if your transaction log files unexpectedly grow. Of course, you should try to avoid autogrowth events altogether.
The prior default of 10% autogrowth has led to so many problems over the years. I’d like new database files (MDF and NDF) to have a similar default as well.
