2.2.6 Performance Tuning for Windows XP
Windows XP has registry entries that you can use to tune SCSI I/O
performance for certain configurations. The tunable parameters are large
transfer block size support and guaranteed number of concurrent I/Os for
a particular SCSI bus.
By default, the LSI ScsiPort and StorPort miniport drivers provide
optimum performance in most standard computer systems. Some
nonstandard systems require fine tuning to obtain peak system memory
utilization and performance. If you observe less than the advertised
functionality and performance on any platform after installation, contact
LSI Technical Support. Go to the LSI technical support home page at:
http://www.lsi.com/support/index.html#hotline
and call the listed number for assistance. LSI can provide additional
registry settings to customize the driver for specific systems and
applications.
