Data type


Default value


0x0–0xFFFF ( 0–65,535 bytes )

0x10 ( 16 )


Specifies the amount of data that must be present in the character-mode buffer of a named pipe to trigger a write operation. If the amount of data in the buffer meets or exceeds this value, it is written immediately. Otherwise, it is retained in the buffer until either more data is added or the value of the CollectionTime entry expires.

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

Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits it.
