    Hi,

    I have a dual e8500 running at 3.13 ghz, and I use nod 32 for
    disinfecting externally attched drives as part of my work to disinfect
    crippled infected pcs via a usb to sata interface.

    If I bought a quad core pc, would the scanning of those hard drives
    be any quicker due to the extra 2 cores availible within a quad cpu,
    or is it a waste buying a quad cpu.

    So basically will I see a difference with nod 32 v4 with a quad compared to a dual for scanning speeds?

    I only use the dual pc for disinfection, So it not as though I run
    simutaneous tasks at the same time.

    Thanks Andrew

    If you scan 4 different files at a time, the scan will be completed quicker when run on a quad-core machine than on a dual-core.

    But is the scanning process limited by HDD speed or CPU speed?

    It depends, but basically it's limited by the cpu. However, if one was to run several on-demand scans of files at different locations on the disk it would make the disk heads move forth and back continuously.

    Hi,

    All I would be doing is one scan of a drive but with a quad core compared
    to a dual core, will the time it takes for that scan be halved with the quad core cpu? - or is nod32 not that effective at using all cores when doing a single scan?

    some programs use all cores if properly written, others have been optimised
    for just a single core or possibly a dual, so is this the case with nod32 64 bit?

    Code emulation is not a kind of task that could be split between several cores. So basically we can say 1 core = 1 scanned file at a time. You'd benefit from multiple cores when performing several tasks at once (e.g. running several on-demand scans).
