Performance average

[hsc]

Hey


Just a quick question about Topdesk on Vista Buiness.

When I run Topdesk 1.5.3, it uses between 8% and 15% CPU power constantly. Even when my system is completely idle, it stills uses that same amount of CPU.

It should be said, that Topdesk works perfectly when I use it, so i'm just interested in knowing if this CPU usage is normal.

My system is a Core 2 duo T7200, ATI X1600, 2GB RAM.


Best Regards

Hi,

TopDesk shouldn't use that much CPU, it should use around 2-3% every few seconds, then drop back to 0%.

What other applications are you running at the same time as TopDesk? What kind of of desktop background are you using, and if it's an image what's it's dimensions? Does changing or removing the desktop background make any difference?

[hsc]

I have no other programs running, other then trillian and firefox.

The background picture is 1920x1440, and i'm running 1680x1050 screen resolution.

I changed the background to a solid color, and then it dropped right down those 2-3% you said!!!

So that did it. But it is a bit disappointing not to be able to have my favorite background

I'll try to experiment a little with different backgrounds...

Hi,

Thanks for looking into the problem. It may be that there's a bug with the desktop wallpaper detection under Vista, in that TopDesk is constantly trying to snapshot the wallpaper. This would explain the CPU usage you're seeing. We'll investigate the issue further to determine the cause.

Hey,

Got it to work with a wallpaper of my choice now

I thought that it might be a problem that the proportions of the wallpapers were not the same as my screen resolution. So I found some that were, and then Topdesk only uses 1-3% CPU power.

So maybe theres a problems on vista with resizing the wallpaper to fit the screen resolution?

Just a thought

Hey again,

I was a little fast to come to an conclusion.

The thing is, that when I set the wallpaper to a solid color and then set then wallpaper again, but through firefox, it works. If I take the same wallpaper and download it instead, and then set it normally through right clicking on the desktop, then Topdesk uses 10-15% CPU power again. Kind of strange really

Also, when the UAC prompts me for administrator rights, the Topdesk icon turns red and stops working. Is this a known problem in vista?

[OtakuSupport]

By design TopDesk should disable itself when the UAC prompt is displayed, but it should re-enable itself when the prompt goes away. Does this happen?

We're still investigating the desktop wallpaper issue, but haven't found a way to reproduce it yet.

Hello,

I'm evaluating TopDesk 1.5.3 on a Windows XP Pro SP2 Brazilian Portuguese machine.

I noticed the same bug: when I use a BMP centered wallpaper (1440x900, same resolution as the desktop), TopDesk uses 15% of the CPU time in average. I'm monitoring it with sysinternals Process Explorer. The machine is a laptop with an AMD Turion64 processor and I still have more than 100MB of free RAM.

When I remove the wallpaper, the CPU usage of TopDesk drops to 1-2% every few seconds.

I've just checked with sysinternals Process Monitor, and TopDesk is doing the following actions in an endless loop a LOT of times per second while I have the wallpaper:

It's a problem with detecting the desktop wallpaper change, but at the moment we're haven't determined why it occurs. Does changing the desktop wallpaper help? What are the dimensions of desktop wallpaper you're using?

[Woonjas]

I have no background imagel, just the default solid colored background.

Woonjas: What CPU usage do you see?
