Well...

I don't compose Office Stuff. I do code, but usually want more than
one window open for editing and compiling. I don't play video games
on my computer, nor watch movies. The only other thing I really do
is research the web, or read e-mail, both of which require network
connections.

I suspect that most of the slowness for *my* computer has nothing to
do with that so much as that Linux eats memory like there is no
tomorrow. So loading *anything* requires retiring a bunch of cache or
swapping virtual memory. My CPU is hardly ever loaded more than 20%,
and usually much less than 10%. When it is slow, I hear the disc
going nuts.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
