I thought that I would be really smart earlier today and decided (which I have never done before) to open an RSS feed in "All Tabs" in Firefox 10.0. As a result there were something like 250+ tabs opened. I then ran the System Monitor to see how much RAM I was using. 1.4GB. OK. No hassles. 2.6GB left. But then I looked at the cpu usage. It showed that I was using around 1,705% of cpu. Repeat, 1,705% of cpu. Now, I ask you, this is an AMD 32-bit, single core, AMD Athlon XP 3200+. Because the number doesn't really mean what you are assuming it means. It is just a metric, useful in relation to itself, higher just means higher, lower means lower, other than that it doesn't actually mean much of anything [it certainly doesn't mean what percentage of your CPUs registers are in use, transistors in use, or "capacity" (whatever that means) is in use]. %-of-CPU is actually a pretty crappy metric. If you are interested in system load pay attention to load-average, a metric

Which then makes one wonder why somebody would waste their time in writing a program which gives meaningless crap.
And thanks for your response - it only confirms my thought that you cannot trust nuthin' or no-one any more in this world :-) .

Relative values are only meaningless when there is only one of them. IE, the very first second of output before the first refresh/update, and only the very first time you ever run it. Every one after that is meaningful.
Is that right? Golly. I ran it again tonight and refreshed the sheebang several times - and this time I even got a figure as big as 10,314% of cpu.
It's amusing that you are so mystified by something so common and ordinary considering how strong your opinions are on occasion.
I adore being mystified especially when the results keep going up and up each time :-) . BC -- Aspire to inspire before you expire. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
