If you increase the number of buffers that the redirector reservers for network performance, it may increase your network throughput. Each extra execution thread that you configure will take 1k of additional nonpaged pool memory, but only if your applications actually use them. To configure additional buffers and threads, edit:
Modify or Add Value of type REG_DWORD for:
MaxCmds The range is 0 - 255 and the default is 15
MaxThreads Set it to the same value as MaxCmds
You may also want to increase the value of MaxCollectionCount. This REG_DWORD is the buffer for character-mode named pipes writes. The default is 16 and the range is 0 - 65535.
