Performance hit with Avast Free 22.5 and later versions
« on: December 11, 2022, 07:56:39 PM »
I like using old PCs.  It's a bit like my other pastime which is classic cars, in my case a 1958 Wolseley 1500.  Old PCs of 2006 vintage are slow.  Mine runs 64bit Windows 10 Pro 22H2 and it runs well with Avast Free 22.4 but with version 22.5 and later there is a very perceptible sluggishness.  This also applies when trying to use Avast One.  People with the latest sizzling tech won't notice a thing of course.

I guess that the devs don't test on a 2006 vintage PC with a 1.83GHz Intel Core Duo and 4GB RAM.  Do they quantify performance reductions or gains from one Avast version to another?  I wish that they could put their collective fingers on why this performance difference occurs and so be able to improve performance.  Then I can satisfy my craving to run Avast Free 23.?? on my Toshiba Satellite Pro P200.  It has such a beautiful display screen.

Well old or not if you could upgrade your system RAM to 8GB (don't know if that is possible on your motherboard) I feel sure you would notice a difference.  When ram gets short a lot of swapping out to the swapfile takes place and this can have an impact on performance.

Also I don't know how many cores your old CPU has as that too can take a beating during heavy activity.
Though this says only two cores - https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+Duo+T2400+%40+1.83GHz&id=730

The typical maximum RAM usage is 2.5GB and paging is much speeded up by a SSD.  I gave Avast One 22.12 a go today and the Tosh P200 laptop was dead slow.  Go back to Avast 22.4 and it is very responsive.  There is a big difference in perceived performance.

The processor is an Intel Core Duo 1.83GHz.  The only difference in performance is when I use a recent (post 22.4) version of Avast.  There is no AV worth using except Avast and other AVs are performance cramping.  Oh lackaday!

The only thing electronic in my 44mpg Wolseley is the voltage regulator.  That's why these ancient vehicles ar so nice to drive.  There's nothing between my brain and the wheels except for my hands and feet.  0 to 60 in 25 seconds.  It's slower than my old Tosh laptop.

I'm now using the nice Avast firewall (RIP Agnitum).  I appreciate the intelligence installed in it.  Avast One works very well and I use it exclusively on modern hardware (that's post 2010).

Happy Christmas David.

I miss the old Agnitum Firewall Pro, I paid for a lifetime license and then they got bought out several years later.

Same here.  I guess that the Avast firewall has intelligence embedded in it which is beneficial to the Avast user.  Outpost asked a lot of the user's own knowledge.  My use of it required a lot of guesswork on my part since my knowledge is still pretty thin in this area.  Avast has clearly done research to compensate for my inadequacies.  However, I did enjoy tinkering with Outpost settings.

I accept that Bob.  I would like to be able to confirm my suspicions that Avast 22.5 included changes which added added more overheads to system operations.

Happy Christmas.

@loungehake Was Avast slowing the PC all the time, or just for 5 or 10 mins from startup?

The performance effect is from startup to shutdown, whether that be five minutes or five hours.  I realise that Avast works very hard just after startup while virus definitions are updated.

Same problems here with Windows 7 on an old Celeron with 4 gb
