Wait Type PREEMPTIVE_OS_CREATEFILE

The wait type PREEMPTIVE_OS_CREATEFILE is ranked #74 by Stedman Solutions and Database Health Monitor.

Wait statistics, in the context of SQL Server, refer to the amount of time that a query spends waiting to access data in the database. When a client application requests data from the database, the request is placed in a queue and the client application must wait for its turn to access the data. The time that the query spends waiting is called a "wait" and is tracked by SQL Server. This information can be used to identify potential performance bottlenecks and optimize the performance of the database. Wait statistics are commonly used by database administrators to diagnose and troubleshoot performance issues in SQL Server.


SQL Server is a popular database management system that is used by many organizations to store and manage their data. One of the key performance metrics for any database system is the amount of time it takes for the system to respond to queries from users. One of the wait types that can impact the performance of SQL Server is PREEMPTIVE_OS_CREATEFILE.

The PREEMPTIVE_OS_CREATEFILE wait type occurs when a process in SQL Server is waiting for the operating system to create a new file. This can happen when a process is trying to create a new file on the disk, or when it is trying to access an existing file that is not currently available in memory.

This wait type can indicate that SQL Server is having trouble accessing the files it needs to perform its operations. This can be caused by a number of factors, such as slow disk performance, high disk usage, or insufficient memory to store the files in memory.

To address this issue, there are a few steps that you can take. First, you can try optimizing the performance of your disks by defragmenting them and making sure they have enough free space. You can also try increasing the amount of memory available to SQL Server to see if that helps.

Another solution is to optimize your queries to minimize the number of times that SQL Server needs to access the disk. This can be done by using indexing, or by using other performance-enhancing techniques such as parallelism and query hints.

In summary, the PREEMPTIVE_OS_CREATEFILE wait type in SQL Server indicates that the database is having trouble accessing the files it needs to perform its operations. This can be caused by a variety of factors, and can be addressed by optimizing the performance of your disks, increasing the amount of memory available to SQL Server, and optimizing your queries. By taking these steps, you can help improve the performance of your SQL Server database and ensure that it can respond to queries quickly and efficiently.
