during the last few weeks, I heard some comments that avast v5 is slowing down web surfing (cutting download speeds to half etc). As we’re not able to simulate the problem here, I’d like to ask for your help.
If you’re one of the people experiencing this problem, could you please tell us how exactly did you measure the difference? (with / without webshield) – i.e. how did you measure the speed? Did you use a speed test? Which one, exactly (URL)? What’s your speed with, and without webshield? Etc etc/…
The more details you supply, the better. Ultimately, we’d like to be able to reproduce the problem in our lab.
Also please note that stopping WebShield will drop all downloads in your browser!
I realize the Turion has much greater processing power and that’s the reason for the difference, but not everyone has computers with the power to compensate for WS’s drag on their systems.
What does the CPU usage chart show when you max out the bandwidth with WebShield enabled? (I mean on the Sempron box). Do you see any peaks in the AvastSvc.exe process?
I have a drop of about 3-4 Mbs with Web Shield ON. I tried Web Guard ON with AVIRA PREMIUM and the drop is about the same, a little bit less. I guess it’s only normal considering that a Web Shield has to do its work (stupid but true…!). I’m noting AVAST 5.0 FREE to be refractory to my 2 computers home, now I just cleaned my Vista one of last year PCTOOLS AV bad uninstall and would like to try again but after the fifth time this year I’m a bit uneasy. Seems to work perfectly well on some computers but as in Antivir you still have people that have problems with their AV. Avira Premium seems to go well on my PCs. I don’t understand. Ideally, WebShield should not interfere with internet speed. You can GOOGLE “bandwidth speed” and find a battery of web sites giving you the tool to measure your internet speed but each one of them will vary a bit in giving you the result. Overall for a connection with high speed internet (naked 7Mbs) you’re slowed a bit. I guess on TGV connections you don’t even feel it, but most of us have high speed don’t they? ??? PS: I have direct connection to cable
I’d say Vlk is interested in the CPU usage - as shown e.g. in Task Manager on the Performance page.
(Though I’m not sure how to show the “chart” for a particular proces (AvastSvc.exe) - other than watching the CPU usage on the Processes page.)
As I said, I have a big PEAK each time I go on a new web page with Web Guard ON which as I said slows down the internet connection as much (equivalent) as AVAST’S Web Shield. So CPU usage is then MAXIMUM. :o
off topic /my wireless connect is the pits, plus bandwidth congested, struggle to bring up 1 Megabit, wrong time of day, but at least broadband is not down or I would be on dialup 53.3 53.6kbps. That said, I can surf comfortable at 1Mbps with many pages open.
well there is some difference Vlk but I dont really notice it much. I try again later and see what is same.
I’m not sure about the date and time - from what else that I see, the tests are supposed to be live.
Everything in screenshot below.
I have included a ping test as well in case it helps
Edit - its midnight now on same day and broadband has been down for 3 hours now - I’ve been on 53.6kbps, lucky forum is an easy make on dialup speed - nothing bad avast 5 might do could be worse than this and happens all the time ??? ??? ??? - I try phone Vodafone NZ and I get redirected to Eygpt cos they doan work after hours here ??? ???

These were my results with the AVAST’S WEB SHIELD ON a few weeks ago and they are still valid with AVIRA’S PREMIUM WEB GUARD now. But it can vary a bit from day to day, as of example my upload speed is most of the time unaffected at 0.78 Mbs while always with Web Protection I can get between 3.8-5.5 Mbs, depending of day. I use the Easy test site.
Have an AMD Athlon 64 3500+ 2.20ghz, 4gbs of ram, 8600GT Video card
Most of the day i use Second Life 3D game that uses 100 percent CPu all by itself, See Some Lag at TImes, but i just consider it a Second Life issue and don’t worry on it, been using Avast 5 since it was released, as well as when the beta stablizied as well. Rock Slid Product, Not sure if the Webshield causes me issues or not–i’ll have to test it and see for sure, perhaps when i’m not using Second life(whenever that is)
I can do a speedtest now with Second Life open, and Webshield on–so i will right now and get that for you, will do one with it on, and one with it off and Intelligent Stream Scanning is on
Download With Webshield on, and Intelligent Stream Scanning: 1571(DSL Rated for 6016kbps)
Upload: 613kbps(rated 768ks)
Think Second life is screwing up my readings, will redo later tonight
Here is my TEST Image, hope it helps to solve this issue. And my system settings are in my signature, so i think in slow end computers, it’s because the system settings they have (CPU, memory, HDD, Mother Board, etc.) , because they can’t work as fast as new end computers with AvastSvc.exe process. By the way, i have 2MB/s DSL Connection.
I’m also experiencing a small slowdown :-[
Using Avast Free 5.0.454 and ADSL 20mbit download,1 mbit upload
Wend webshield is on i get around 8mbit download with avastsvc.exe using sometimes 40% of the cpu :o but with webshield off i get around 15mbit download
That’s hardly a reason really. Atom N270 1,6GHz (single core, 2 threads, in-order) doesn’t even come close to Turion, yet i’m getting perfectly normal speeds on netbook for 8Mbit connection (through wireless router) using avast! 5 Internet Security.
Also, if you are experiencing the issues, does it make any difference if you open the avast UI, navigate to Real-time Shields, Web Shield and uncheck the “Scan web (HTTP) traffic” box?
