What are the differences between OpenBSD and Linux?

And related to this, how's the multi threading story? Once upon a time the folklore was that Linux was doing well, FreeBSD was also good, but the other BSDs were lagging.

Nota bene: my info is from 2010 or even earlier.

I’m no expert on the internals, but with an appropriately configured set of resource limits for your user class, OpenBSD is not much slower than Linux for multithreaded tasks like web browsing. I think they disabled hyperthreading by default for security but I don’t have a device with those capabilities anyway. Firefox spawns many threads on all four cores of my desktop machine and performance is plenty good.

Firefox uses processes, not threads for parallelism, doesn't it?

Yes, but I’m not sure if we’re talking about hardware “threads”, the OS concept of a “thread”, or what Firefox calls a “thread”. Maybe someone who knows more about what they’re talking about could clear it up?
