Wonder how it knows current upload/download speeds -- is it testing it very often
if so, wouldnt that use up all your bandwith then?
I haven't noticed any resource consumption other than about 5 MB of Ram. I would guess that it queries WMI info every few seconds. I have a freeware Tray Disk LED simulator from another programmer that gets the disk activity from WMI. I sense no performance penalty and leave it enabled when I defrag.
Wise claims they did a lot of testing with the aim of leaving Performance Monitor in the tray all the time. From using their other utilities I have a pretty good feeling about their software.
I just ran broadband speed test
with Wise floating window, without, then with it running again. I got some variation in the speed. But I think it is just variation from run to run as there are a lot of people on the WiFi at the college here. In fact the first run with Wise floating window running was the fastest.
I like it because even though the font in the floating window is pretty small, it is white text on black background so even with my semi-blurry vision I can read the numbers. And the CPU activity uses a little rectangular blue graph. I think it is pretty cool. For example if you left click on the Ram usage number it brings up a window with a pie chart of used/free physical ram and a list of processes and the ram used by each. If you left click the CPU Temp number it brings up a window with indicators for CPU, GPU and HD temps.
I think you'll like it if you give it a try.
