Longhorn (and XP, 2000, etc) Speed Burst

Well, while configuring my PC to try to get some speed benefits whenever possible I came across this cool little util from Intel, sitting on that disk of stuff that came with my PC (and got ignored after I repaved it), called Intel Application Accelerator. 

This little app, with info here improves the i/o subsystem for Intel chipset mobo's.  The startup & compilation under longhorn is pretty noticably improved...

Best of all, there's a version for RAID, too...
