Shlomi,
MooseX::Declare has a well known and fairly heavy overhead cost and
anyone who uses it should be well aware of this so they can make the
choice as to whether the syntactic sugar it provides is worth it.
However your comparison (as has been pointed out) is not really fair
since Class::XSAccessor and MX::Declare are absolutely not in any way
equivalent. A more relevant comparison and valuable discussion would
be the difference in overhead between MX::Declare and plain old Moose.
Also, don't feed the trolls please.

You're using /usr/bin/time, that makes this the most useless
benchmark
in the history of mailing lists everywhere.
We'd better be careful when you're flinging these hyperboles.
You're not even testing
one thing, you're testing eleven (t/001*-t/0010* + t/99*) that
presumably all have `use Moose`. You're unrevealing statement is akin
to this, "MooseX::Declare has high startup costs." And, that's why
the
trend wagon still makes frequent stops at Mouse.pm, and the 3 year
old
idle project MooseX::Compile still gets talked about as an "upcoming
fix".
(28-2) / 11.0
2.3636363636363638
Actually, it's more than that because two tests exit at the start
due to
missing dependencies or environment variables.
Seriously, MooseX::Declare adding less than 2.36 seconds to start up
on an old machine.. That's the post..
Where do you see the less thing? It gave you 2.363636.
First of all, 2.36 seconds is noticably a lot, especially given
there are a
large number of tests which together add up to 20 extra seconds and
an 11 time
increase. On the same machine, my solver can solve on average 1,013
deals of
Freecell in those 2.36 seconds.
Furthermore, while it's a Pentium 4 2.4 GHz machine, which is a bit
old, I'm
hesistant to call it underpowered. I was told that a Pentium I 100
MHz is
roughly as fast as the Cray 1 supercomputer used to be, and a
P4-2.4GHz is
several measures faster than the original Pentium I. On my P4-2.4GHz
machine I
can comfortably run KDE 4, and lots of other programs.
Finally, I'm not in the mood to unnecessarily wait 28 seconds for a
test suite
to run, when it should and can take less than 2 seconds.

Shlomi Fish
