    Not sure if this is a good place to bounce this question, but here goes.

    Have a Dual Xeon E-5 2643on a SuperMicro motherboard. with an LSI MegaRaid SAS 9260-8i

    Windows Server 2012 because Standard Edition of Windows 2008 R2 is apparently crippled in it's "licensed" RAM usage)

    Interrupts stay at a steady 1.23% and peak @ 2.x% (most Interrupts are around .03 to .07%)

    A peek at XPerf told me that storport.sys was primarily responsible for most of this.

    I assume that this is used by LSI/RAID?

    Is this normal and merely overhead that is a result of the contention of having Dual Processors. Or normal for LSI?
