Data type

Range

Default value

REG_DWORD

0–255 ( network control blocks )

15

Description

Specifies the maximum number of network control blocks that the redirector can reserve. The value of this entry coincides with the number of execution threads that can be outstanding simultaneously.

Increase this value to improve network throughput, especially if you are running applications that perform more than 15 operations simultaneously. However, because this entry also limits the number of outstanding execution threads, your network performance might not improve. Each additional execution thread uses a margin of 1 KB of nonpaged pool when the network is at capacity. However, these resources are not consumed until the user references data in the network control block.
