Data type


Default value


0–65,535,000 ( milliseconds )



Specifies the maximum time that application data waiting to be written can remain in the character-mode buffer of a named pipe .

The redirector writes data from the character-mode buffer when the amount of buffered data reaches the size threshold established by the value of the MaxCollectionCount entry. However, if the application has written at least one byte of data to the buffer but not enough data to reach the size threshold, the contents of the buffer are written when the time specified by this value expires.

Increasing the value of this entry can improve the performance of named pipe applications. However, it does not affect applications, such as SQL Server applications, which do their own buffering.
