John, you're saying that NetBSD performs in an inferior manner to
FreeBSD. I haven't seen any evidence of that. This is not
something that I'm hearing from other people. I suspect that it's a
prejudice, and not a fact. This is why I'm asking you about
benchmarks. If you haven't run benchmarks, how do you know? The
answer is that you don't. That is what I am trying to point out.

I'm talking about the complete rewrite of NetBSD's VM code, which
happens to correct the problem that you were talking about when you
brought up NetBSD's poor performance under paging at the FreeBSD BOF
in New Orleans (or was it San Diego?).

I don't know so what. That's what I'm asking you.
