I am so tempted to install this after a 15 year break...

You can try it right now inside virtualbox, and 20 minutes later you realize that it is has all you need. After a few days, you'll notice that you spend most of your time inside the virtual machine, and then it makes sense to turn your setting upside down and work directly on the saner system.

Is this on all architetures or just Intel's Hyperthreading? I'd imagine that other CPU's with hardware threads (especially the 4 and 8 way Sparc T series) would be quite hobbled in terms of performance with this change.

Linux is a depressing mess after you've used OpenBSD. Such a high quality system, with stellar documentation. It's unfortunate that Linux has become so popular even though the BSD's are so much better. A bad historical accident. Damn you Linus...

How well does the inverse works - running VMs in OpenBSD to use Windows, Linux? Is it for example possible to run Virtualbox with good performance in OpenBSD?

I'm tempted at using OpenBSD as OS, but need to run things like MS Office. A VM is probably the easiest way to do that.

As far as I know this is not possible. You can always do it with qemu but it wouldn't be practical.

If libreoffice is not appropriate for your needs, you may try googledocs inside the browser.

I run OpenBSD as my border firewall which it handles very well.

One thing I wish that OpenBSD devs would change in their philosophy is the --help messages. Many commands simply offer a list of switches, as if that's somehow helpful. Sometimes you need the detail in a man page, but a lot of times you don't and it would save so much time and energy to have a succinct list in the --help message itself.

# syspatch --help usage: syspatch [-c | -l | -R | -r]

Should be specific to Intel's Hyperthreading, according to the ml announcement [0]

No need for harsh feelings. BSD value will have its time. Now don't read about perl vs php :p
