Nod32 4.0 scans quicker on 4 cores or same on 2 cores?

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).
