Assume that you have SQL Server 2017 on Linux or Windows. If the database has a large number of memory optimized tables or memory optimized table types then the database recovery may take long time due to waits during compilation of the memory optimized tables. If you do a wait analysis from sys.dm_os_wait_stats, you may notice PREMPTIVE_OS_FINDFILE or PREEMPTIVE_OS_CREATEDIRECTORY wait types during recovery.


This issue is fixed in the following cumulative update for SQL Server:

       Cumulative Update 5 for SQL Server 2017

Note: To speed up the recovery, you have to enable Trace flag (TF) 9944.

Each new cumulative update for SQL Server contains all the hotfixes and all the security fixes that were included with the previous cumulative update. Check out the latest cumulative updates for SQL Server:
