Default value

REG_DWORD

0x0–0xFFFFFFFF ( milliseconds )

0x1F4 ( 500 )

Description

Controls the maximum time at which the redirector backs off on failing, nonblocking, named pipe read operations.

This entry exists to prevent an errant application from overwhelming a server with nonblocking requests when there is no data available for the application. You can use the backoff statistics to optimize this entry to be more efficient for an application that uses nonblocking named pipes (except for SQL Server applications).
