That's incorrect. I gave a perfectly good reason, it is changing the way
the system expects to be configured. That is generally a bad idea, and
sometimes a very bad idea.

There are many modes you can select that are certainly bad when you
start looking at sysctl and kernel settings.

Actually, that is also incorrect. The compression, much like the
encryption in FileVault 2, doesn’t even go through the CPU.

I don't care what YOU do, I care that you are recommending it to
others.

Yes? And? Mentioning your name doesn't make it ad hominem. Saying the
idea is stupid because you have purple spots and drink rotted pig's
blood would be ad hominem.

You are an ignorant fool. Saying that something someone is doing is
stupid is not ad hominem. Saying it is stupid BECAUSE they are doing it
is. Saying nothing about the idea at all and simply saying that the
person presenting the idea has bad breath and therefore should be
ignored, that would also be ad hominem.

Calling you an ignorant fool is also not ad hominen, it is simply a
statement of fact. And since your foolish ignorance is not my reason for
saying your idea is stupid, no ad hominem at all.

I never said YOU were stupid anyway, I said what you are doing is
stupid. I am not directing the argument AT THE MAN, I am directing it at
the idea, the action, the behavior.

> I don't mind reasoned debate,

Yes you do. Changing system settings, especially low-level ones, is
dangerous and foolish and yes, even stupid. You claim there is a
benefit, but show no evidence of this. Unless you are using the iOS 6
virtual machine in XCode, there is absolutely no benefit to changing
this setting. None. There is very great risk. Maybe not now, maybe not
tomorrow. But almost certainly at some point.

You have repeatedly ignored this reasoned argument and instead dismissed
it with hand-wavery.
