| The wait type PREEMPTIVE_OS_PIPEOPS is ranked #1 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. The PREEMPTIVE_OS_PIPEOPS wait type indicates that a task is waiting for an operation on an operating system pipe to complete. Pipes are used for inter-process communication, and this wait type is often seen when a task is waiting for a response from another process. This wait type can also occur when a task is waiting for a response from a remote server or when it is waiting for a response from a service that is running on the local server. The length of time that a task spends waiting on this wait type can be an indication of the performance of the other process or server that it is communicating with.
