Now we're finally progressing. And I believe we can progress even more
efficiently if you can provide the needed information instead of
accusing my "hatred" (which I sincerely do not have; an anonymous person
on the other side of the screen isn't significant enough for me to
develop hatred for. My previous post was triggered by those aggressive
statements still occasionally appears between your words).
So I would like to ask again about your display settings (since your
mail seem to suggest that you are using an graphical interface), because
you still haven't give me enough infomation to rule out that possibility:
1) If you are using the video tty console (e.g. without X), which mode
are you operating on? The BIOS with VGA text mode, the BIOS with
"graphical console", or the UEFI console?
2) If using X, I would like to confirm your X settings as stated in my
previous email.
And since you were mentioning 4K video performance, I would like to
confirm that the 4K video test is actually conducted on OI, because
graphical performance on another OS clearly does not matter that much.
In case you are still not convinced, here are some simple performance
test results, conducted by untaring a gcc 9.3.0 source tarball, on the
same VM running OI:
1) BIOS, Graphical console: 7.65s user 59.54s system 1:14..64 total
2) BIOS, VGA Text console: 8.79s user, 1065.31s system 18:11.63 total
Yes, this is not a typo. I am as surprised as you may are, so I
tried again:
8.61s user 1060.95s system 18:07.12 total
Apparently VirtualBox's VGA Text implementation is not incredibly fast.
3) ssh localhost -p <guest's ssh port>: 7.94s user 13.22s syste, 32.183
total
4) with `> /dev/null` (e.g. no output at all): 7.35s user 11.72s system
30.844 total
There's a 35x performance difference between VGA Text and null, so I
would like to rule out that variable before digging deeper into it.
That's why I'm asking for details on your display setup.

I will took me hours to write a very long mail to answer each of your points.
So I will give you a short summary: I have tried it on both physical machine
and virtual machine, my graphics performance is good on the physical machine, I
could watch 4K video without much tearing. I would say it's slow in any
circumstances. Not only the output printing is slow. I really measured the time
it took to complete the jobs to do comparison.
Hater gonna hate. I know you hate me. So I don't mind.
The fact is both Linux and OI are using bash as their default login shell for
user, though.
Please do a little investigation before you post and don't let your plain
hatred for someone to ruin your investigation.
I didn't asked to add any Linux shell at all. Please keep that in mind.
