I know you’ve seen the complaints about Firefox, etc. I noticed it spiking the cpu, etc.
Had occasion to snap my hard drive into Keyron’s computer. It is identical to my computer with three exceptions:
1) It has a DVD burner on it.
2) it has less physical memory
3) It has an Intel 2915 wireless card, mine has the Intel 2200.
I note youtube works, everything works and the cpu isn’t hammered. I also note no dropouts on the net connection. The behavior I was seeing was system threads on the cpu using 40% or more.
What happened was the wireless card was generating too many IRQ’s – sucking up system resources to service those interrupt requests.
The end result, new wireless card for my computer is coming.
