Well, if it was in the same tone as my initial posting, there should be no problem. I merely, in a
polite way, pointed out that (performance != microbenchmark) which is correct. I pasted that email
below, so anyone could see there is nothing wrong with it. Hence, I am sure everyone was on the

You were to told to spam freebsd-performance. By whom? If someone told you to kill FreeBSD core,
would that be an excuse?
I did not read slashdot. I am not even subscribed to NetBSD lists, but I look through kernel
related traffic for ideas.
> That said, I think an apology is in order from your side.
Apology for what exactly? Is anything that I have written so far inaccurate?
How about we continue this in private? Frank asked to discontinue this thread I think it relates to
both of us.
PS If you were not the one who started thread on FreeBSD, why did you not tell anyone that someone
impersonated you? People (including myself) have written you. The email address work (as we know
now). In fact there are other reasons for me to believe you were not impersonated, but I believe
it's beyond the scope of this thread. Obviously, it's not totally impossible. If you started that
thread, then it's irrelevant whether you are subscribed or not. You said many FreeBSD people told
you benchmarks are useless. You did not mention up until now that ALL of these many people were
afraid to post to a public mailing list. Otherwise, they have been naturally told. Microbenchmarks
are NOT useless. They benchmark performance of some aspect of a system. That's why people run them.
However, we can hardly accept that these misterious cowards represent FreeBSD community.
PPS That was rather large post-scriptum
The benchmark suite in question is not bad, but it's a microbenchmark suite.
BTW, when we used the suite to tune kernel for ourt needs we had to change many things.
As of a year ago some tests had to be modified, otherwise we might start tuning for the wrong
goals. The title of this email and the article is NetBSD beats FreeBSD in performance should be
changed to NetBSD beats FreeBSD on comprehensive microbenchmark suite. I don't remember who it was,
but someone posted results of real server tests. These were in favor of FreeBSD. I doubt that much
changed since last year but who knows ... Maybe NetBSD is better, but this is not something that
could be concluded from a microbenchmark.
