Installing the Device Driver for Windows 2000
3 Large I/O request performance enhancement:
Performance enhancement for a large size I/O request could
be done by increasing the maximum number of scatter-gather
lists or NumberOfPhysicalBreaks used by the SCSIPORT
driver. This is only needed if you are running a special
application that takes advantage of large I/O.
The default when not specified in the Registry is 17 elements or
a maximum transfer size of 64K. The Registry file provided
will change the value to 65 elements or a maximum transfer
size of 256K.
