[OpenIndiana-discuss] Shell to use?

I'm posting on MX Linux, not OI. As I said, my stupid BIOS hates OI.
I have tested on two instances.
First, physical machine.
This is when I removed all disks from my system but only keep the OI disk, OI could boot and functional properly.
Only dual boot triggered the stupid BIOS.
I watched 4k videos on this system. Using Pale Moon which I compiled from source. Our outdated Firefox can't deal with 4k. It will just crash.
My desktop is an out of the box MATE desktop of OI. No customization was made.
The terminal emulator is of course Mate terminal. And it's slow with this terminal.
On physical machine, OI is always run as a graphical system.
The console font of OI is too bad. It hurts the eyes.
OpenBSD is much better. I can work with console OpenBSD, but can't stand console OI.
Second, the VM.
It's a VirtualBox VM. The host is MX Linux. 4 cores 4GB of RAM. My host have 4 cores 8GB of RAM, I give the VM as much I could give.
It's a minimal text based installation.
Both accessing the console using VirtualBox or use ssh on XFCE4 Terminal on the MX Linux host, everything is still slow.
The fact is I found the output is a bit faster when using ssh.
But it could be just because OI's console font is too bad and the good looking font on XFCE4 Terminal that fooled my eyes.
I didn't make this as a statement, because I didn't measured the actual time spent between them.
Hope this help with your investigation. I can provide no additional information.

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.
