Or we can sit down Richard Stallman, Linus Torvalds, and developers from all projects to enjoy a five-star dinner together, so that they can peacefully discuss and settle on a single universal standard. I'm sure they'll all agree. We'll even pay for their food.

We can sell tickets, like a zoo. Best part is we don't even need locks, the discussion will naturally go on forever.

My bad, I believed you were running CORE; for SCALE run watch -n 2 zpool iostat -v.

Code:

Every 2.0s: zpool iostat -v                                                      strikerajr630: Tue Oct 10 20:50:22 2023

At the same time, this is what the windows VM is reporting in task manager

But we were just hearing in another thread about how it was bad that iX developers should have included a PATH for stuff in /usr/sbin? Surely you are not suggesting that dotfiles are a user's responsibility?!?!?!?! (is there no sarcasm tag?!?!?!?!)

At one point, (if I remember correctly), the ZFS commands could not be run as a normal user on Linux. Pretty annoying. And I am talking about actual permissions, not PATH. Had to use SUDO or switch to root.

Are you making the test copying files from the system to a VM inside the system?

Are you making the test copying files from the system to a VM inside the system?

no, the test is a program inside the VM, and the program reads the same 16GB file on every loop. Run time for one loop is about 10 minutes.
