NOD32 heaviness

Has anyone else noticed that NOD32 v 2.7 is getting heavier and heavier in terms of memory usage? It seem to me that now NOD32 is taking twice the memory it used to, back when it was lean. Why is that? I will provide screenshots later to validate, however right now I do not have the time. Thanks.

Looks the same to me. I'm not worried about memory consumption but rather how heavy it is on the cpu.

 

I can't confirm whether it is getting "heavier" or not but compared to the other popular AVs I used to use the current NOD32 v2.70.39 still seems to be night and day "lighter" than they were.

Under my system's task manager the memory usage for nod32kui.exe is 2,732K and for nod32krn.exe it is 26,660K.

Considering most systems today come standard with 1GB to 4GB of RAM then those NOD32's background processes I mentioned use under 30,000K which is only a small fraction (or less than 3%) of the more than 1,000,000K of total memory that comes standard on most newer systems.

Just for a reference it would be interesting to compare NOD32 with the memory usage of other AV programs such as KAV, BD, Avira, NAV, McAfee, etc..

 

I get just over 21k for nod32krn.exe. Absolutely fine for me. And it still feels lighter than anything else.

 

Same RAM use as the other AV XXX.. . but Nod uses +40MB less VM

 

nod32krn - 20,5 MB, nod32kui - 2 MB. Seems to me reasonable if you take into account that new signatures and other engine updates are being released on a daily basis.

 

Well that's a very good point. Memory requirements may be up but CPU usage seems to be low still. That is a problem that I have with the Dr Web beta, my CPU was active all the time.

That is somewhat true. The processes that NOD32 uses are in check. However, as is the case with Dr Web also, NOD32 effects other system processes than inflate system resources.

Can you see the differences here? Everything is the same, other than the AV.

Hasn't changed for me...still in the low 20's.

 

Its memory usage is a bit more than other av's but its performance impact is far less than many others.

 

I guess that's what really counts, isn't it? If the user cannot tell is a product is using more resources but you cannot tell then foes it really matter?

 

mem usage seems not compareable...

WinXP SP2 NOD32 2.70.39

PIII 700 MHz, 256 MB Ram
nod32krn.exe 14.728 K
nod32kui.exe 1.492 K

P4 2,4 GHz,1 GB Ram
nod32krn.exe 23.472 K
nod32kui.exe 2.304 K

Athlon64 1,81 GHz, 1 GB Ram
ekrn.exe 28.832 K
egui.exe 2.138 K

 

Yes, that's why it is not a fair comparison comaparing different machines with different OS's and different amount of installed RAM.

The effect on system performance is the key factor and in this respect NOD is generally considered "lightweight".

 

I have tested virtually every anti-virus engine on my computer (Dell Inspiron 8200) and NOD32 is by far the most efficacious in terms of not slowing down my computer work. This applies to normal computer usage as well as internet activities. Here is the memory used as shown by Windows Task Manager:

nod32krn.exe 22,796k
nod32kui.exe 2,656k

 

Probably fairly dynamic on machines with sub-average RAM (like under 512 for XP)...such as on that 256 meg box..everything has to squeeze in tight. But on several rigs I have from 1 - 2 gigs of RAM...I'm steady between 22 - 24 megs.

 

This post is not a bash or comparison post. I am posting it as it might be interesting for others to see what another av uses as far as memory and CPU
On windows Vista Home Premium

 

@bigc73542: isnt there two avp.exe processes? One takes up the amount of memory shown in the SS you posted, the other takes up an amount of memory comparable to that of nod32krn.exe. Could you post the same data for the other avp.exe process for us to compare with NOD?

Cheers

 

well put it this way on my old pentium 3 with 256mb of ram i dont notice any difference in proformance with or without it.
so nod32 is still very light.
atm im using kis7.0tr and the memory usage is as follows.
one is 3mb and one is 8mb.

Hello.

I have noticed that the same application doesn't consume the same amount of RAM in XP and in Vista. I have a resident app that takes over 20megs in XP. When I put it on Vista, it takes little over 2megs.

That said, NOD is the definite king of resource sparing among AVs.

Cheers.

 

I'm deploying a bunch of HP Business Desktops at a health care client of mine. Some lighter to mid-weight machines..Pentium 4 D 2.8 with 512 megs, XP Pro. They unfortunately come bundled with Symantecs Corp Edition...didn't notice the version.....10.something. I fired up taskman out of curiosity....the scanner process was 50 megs, the another process was 4, and I think there are 5 total? Didn't look for the other 3.

 

Here you go
