Disable command queuing
To improve standalone workstation performance and to improve
performance with some high-performance SCSI peripherals, you should
disable command queuing in the Windows NT Registry.
WARNING
Do not change values in the Registry other than as directed. If you
introduce incorrect values into the Registry, you may cause serious
operating system problems, and you may have to reinstall Windows NT.
If you change values in the Registry that make your system unusable,
you may be able to restart the system and use the Last Known Good
Configuration option to undo the damage. Refer to the Windows NT
Workstation Installation Guide for more information on the Last
Known Good Configuration option.
