All four cores at 100%? We don’t see that kind of spike when we open some other application right? Is it the experience of everyone? Or am I wrong in this?
That first data point is simply invalid. Ignore it. Monitoring software usually report some kind of statistic (mean, median, min/max, etc) taken from measurements over a period of time instead of the instantaneous value when the report is updated. But they can’t do that for the first data point when the application is launched because there’s no time period over which to measure it.
This is the real answer. Other apps might be bottlenecked by IO so the CPU doesn’t work as hard. Get faster disks, the CPU will see more use. Since top is so small that it loads into memory almost instantly, and has no need for further IO, the CPU is free to spin all the way!
People get worked up when CPU usage is high, but unless there’s a resource leak somewhere, that just means the computer is working at full efficiency.
Well it does make sense that the CPU has to work a bit when loading a new program.

Lim t->0 x/t =infinity when x>0
Math - not even once.
I paid for all the cores, I’m gonna use all the cores!
Top revs the engine as a test /s
Unless bottlenecked somewhere else, we would want to see 100 % with everything that takes more than some milliseconds.
