	[..] La nuova VM ha migliori performance rispetto alla vecchia sui
	tipici sistemi desktop ... ma fa fiasco terribilmente su più sistemi di
	quanto non lo facesse la vecchia VM. Redhat, per esempio, non ha potuto
	inserire la nuova VM nella sua distribuzione perché cadrebbe a pezzi per
	i database server, [..]

This is total bullshit. If there's something where the -aa VM is good
are the DBMS, that was designed for it basically, very lightweight,
basically no VM overhead also under very heavy I/O.

If redhat doesn't use the -aa VM into their kernels that's either a
political decision or they're not good enough at the VM. I can tell you
there are an huge number of users very happy about the -aa VM mainly on
DBMS, I know some redhat partner is also using the -aa VM for their
internal DBMS work (incidentally I assume rh kernels aren't good enough
for them?).  I don't care much of interviews, real people will make their
choice about the VM based on facts anyways, you may forbid someone to
try or you may convince someone that doesn't need much VM anyways saying
weird things like "collapse under high load or breaks on databases", but
still it's annoying to read such a bullshit and have people sending
emails to you about stuff that it isn't true.

So if you can proof any of your statements with numbers about
regressions with DB with -aa VM compared to 2.4.9 or
2.4.9+ac/rh/whatever please let us know. I have an huge amount of doc to
proof the exact opposite (the first few impressive emails I found are
attached) and most important I don't have a single bugreport about the
current 2.4.18pre2aa2 VM (except perhaps the bdflush wakeup that seems
to be a little too late and that deals to lower numbers with slow write
load etc.., fixable with bdflush tuning). Mainline VM kills too easily,
this is fixed in -aa VM and -aa VM has a number of other issues
resolved, but mainline 2.4 vm isn't that far either. In the last few
days I was playing with pte-highmem, soon I will spend some time merging
-aa VM into mainline with Marcelo if he likes to.

PS. I know the interviewer and he's usually very accurate, so I don't
think this could be a misunderstanding where you say one thing and they
writer another one just to create troubles.
