NOD32 : perceivable slowdown while surfin'

Hi all,

First of all, I have uninstalled SpyBlocker and restored the host file in its original condition. There's an improvement but it is not blatant.

Next I ran this speed test : Speed Test Link

I have an ADSL connection ( 512/128 ), so for the test I have selected "ADSL" then "Europe".

Here are the results :

IMON ON ("Higher Efficiency")

Communications : 486.6 kilobits per second
Storage : 59.4 kilobytes per second
1MB file download : 17.2 seconds
Subjective rating : Not bad


IMON OFF

Communications : 494.4 kilobits per second
Storage : 60.4 kilobytes per second
1MB file download : 17 seconds
Subjective rating : Not bad

But unfortunately that does not solve my problem : when disabling IMON, everything is OK, when enabling IMON, there is a noticeable lag....

It drives me crazy !!!!!!!!!


NB : In IMON ===> HTTP ===> Configuration, I have :
Mozilla/4.0 firefox.exe ("Higher Efficiency")
Mozilla/5.0 firefox.exe ("Higher Efficiency")

I do not know why ? ( I have only one copy of Firefox installed on my machine !)

 

Hi ive just done this test with the networking feature of taskmanager open, the test was only using on average 15% of the available bandwith i have, so the results are far from accurate.

In my personal expiernce Nod32 is the fastest AV on the market, i notice no lag in internet activity or PC speed at all.

 

Hi Imothep, I have sent an email to Eset asking for further assistance with this matter.

Cheers

 

Just for a test if you use IE instead of Firefox to surf do you see the same slow down with the IMON HTTP scanner enabled as compaired to when you disable it?

 

I don't understand how you are noticing a .2 second lag and a 1 kb difference.

BlackSpear,

It is very kind of you. Thanks

Sweetie,

Could you point me to a link where I could perform a reliable speed test ?


Stan999,

I have switched to IE and there's no difference.


Gauthreau,

I just can't understand why !!! very uncanny

 

Is the slow down that you are talking about more of a 'slow to display' problem, rather than an actual internet download problem? I ask because your speed tests look virtually the same. Do you notice particular times of day/night when things slow down? How about when you are running NOD and running graphics intensive applications like gaming or photo editing?

@imothep - there are various sites and tools for measuring network/internet bandwidth. i know cnet.com and mcafee.com have internet speedometers. the task manager in winxp also lets u view network traffic. dumeter is a utility for monitoring traffic. and btw have u tried repairing network configuration. IMON > setup > miscellaneous

 

Also, have you tried emptying your internet cache - IE and FF?

Neil

 

Hello Imothep,

Just so you and everyone else knows, Eset support dudes are monitoring this thread. Didn't want anybody to think we didn't care..... of course we care. But you've received so many really useful ideas and help from all of the other contributors, there isn't much I or my colleagues here can add at the moment.

I also use Firefox and have had no noticeable slow down issues. I've tried IE and Opera also with again no side effects. I haven't seen any other issues come in to support@eset.com about this recently. Obviously, there will be very slight slow down because IMON is doing his job, but personally, the slow down is hardly noticeable.

Hi all,

Gauthreau,

Yes it is a "slow to display" problem rather than a internet download issue. When disabling IMON, everything is ok : pages (even bloated pages, ie: images and so on) load instantaneously.
I tried to empty cache, I have also uninstalled all my other security softwares (Pest Patrol, Spyblocker even my firewall), the problem remains the same.

WSFuser,

I have repaired network configuration but it has not solved anything

Bandicoot,

I do not know if it is linked to my problem but today I have noticed that IMON did not start. I tried to invoke it manually but it did not run : I had to stop it and reboot my computer to solve the problem. I am going to make another thread about it.

Anyway, I would like to thank you all for your valuable advices and I hope I do not bother you

 

Can you please download and run belarc advisor from here and post the log in this thread. MAKE SURE that you edit out your Windows XP Reg Key BEFORE posting.

Can you also download and run “Hijack This” found here and post your log in this thread.

As this is the part of the same issue, can you please continue posting in this thread.

It’s our pleasure and it also is no bother at all, we will get you sorted out, there is yet to be a system that I cannot get Nod32 running smoothly on

Cheers

 

@imothep - have u tried using cfos or cfosspeed as an adsl modem driver? it seems a bit irrelevant, but maybe it could help.

 

Sorry guys, on my box, I don't see any slowdown.


maybe it's due to USB connection...

 

Hi,

First of all, sorry for my belated reply.

I have uninstalled and reinstalled NOD32 and everything is OK now !

I would like to thank you all for your valuable help

 

Really great to see

Thank you for keeping us up to date.

Cheers

 

I have a cable modem that gives me 5 Mbps (the rated speed from my ISP) on two of my PCs without NOD32 (including a wireless laptop). But with NOD32 on a clean install of WinXP SP2, I get only 3 Mbps tops from the following site:
http://www.computers4sure.com//speed.asp

When I turn off IMON, there is not much improvement; when I stop the NOD32 Kernal Service entirely, the speed increases to about 4 Mbps tops.
However, ftp downloads still work at the full 5 Mbps speed, so it may be just an HTTP artifact from this test site. It is not exactly a hardship situation of course, but my ISP is upgrading my speed to 7 Mbps next month and I would not like to lose a big part of it if possible.

Any ideas? I have not yet tried uninstalling NOD entirely on this PC, but that is the next step.

 

What speeds do you get from this test site on that machine?

http://web100.rit.edu:7123/

 

try here too...
http://www.dslreports.com/stest

 

TCP/Web100 Network Diagnostic Tool v5.3.3a
running 10s outbound test (client to server) . . . . . 761.13Kb/s
running 10s inbound test (server to client) . . . . . . 4.99Mb/s

It looks like this one is unaffected by NOD.

 

From the NJ test site (I am in PA):

2005-01-21 14:46:42 EST: 4719 / 727
Your download speed : 4832495 bps, or 4719 kbps.
A 589.9 KB/sec transfer rate.
Your upload speed : 744558 bps, or 727 kbps.

That is fine too. It looks like only the link I posted is affected by NOD, for some reason. Thanks for the input; it is probably not worth bothering with further.
