I switched to systemd under Wheezy a couple of weeks ago. I had a
small problem convincing aptitude to stop switching back to the
old
way any time that I wanted to install packages from
security.debian.org [3]. After fixing that I have noticed no
difference
from the old way, whose name I have already forgotten. My hardware
has
a built in, intended, delay before start of boot, so I don't
percieve
that boot is faster. Maybe it is. I just can't see it in my
particular
set up. I am much more worried now about the world going nuclear
before systemd gets a chance to prove its usefulness.

sometimes people on this list get somewhat horny when discussing
those things, which are really subjective in the end... they go on
with a mixture of tecno-steronic, 0.02$ philosophy which I can't
stand
:-(
Peace to all, I hope
respect

The speed you can gain by changing an application depends on more than
one parameter.
It depends on the software configuration of the system: switching from
a KDE application to a GTK one ( on a GTK-based desktop ) will allow to
notice resources gains.
But also on the hardware you have: depending on the computer you have,
running eclipse can start instantly ( at least, I guess so, I've never
seen that ;) ), or starting even vim can take more than a second.
Finally, it also depends on it's own configuration: keeping eclipse as
an example, it will be obviously faster if you configure it to load less
plug-ins.
Most of the time, it's stupid to say "my application will be faster
than others which does the same, on all hardwares and softwares
configurations". Except if you publish a fork in which you removed
features, or fixed bugs. And even then, maybe the end user will not
notice the speed improvement because he's computer is too fast for that.
Systemd, as every piece of software, also depends on those points. And
speed is not the killer feature of this daemon, instead, it's easy to
write configuration files ( and not, script files! ).
For me, systemd is not a good choice. Because it does not fit with my
objectives, and would only give me a very limited, if any, speed and
maintenance gain: I like very minimalist systems, where things are
started by hand if and when I really need them. So I do not have a lot
of services. Plus, I am not a maintainer, so I do not have to maintain
starting scripts ( but I need someone to do so instead of me, for now ;)
) and I think that it's easy enough to disable/enable a particular
daemon, since we only need to change a file name and run #update-rc.d
<script> defaults.
But, that's only my use. Normal users uses KDE or Gnome, with tons of
potentially useful daemons started all the time ( cups, sane,
network-manager, dbus, and for some programmers apache, php, DBMS... )
which are really heavy. For those, systemd will really be useful. And
those daemons have dependencies on others, so it will help their
maintainers to use systemd, too.
Note, I did not read the latest trolls. And I do not care if someone
thinks I'm wrong. I have built my opinion on what I really need if
systemd can help me with my own special needs long ago. And I think it
is not a software built for peoples like me. I'm fine with that, and
with Debian's default choice, as long as I can switch to others.
I already manually explicitly ask debian to install lilo and not grub,
no DE but instead a wm plus some specific tools, no "basic tools" but a
hand-made selection of them. I can ask it to install a particular init
system as well, I do not mind.
And people who are really angry about that Debian's maintainer's choice
can just do the same, instead of flooding a mailing list dedicated to
helping other people solving problems. That's what adults should do,
btw. I'm becoming tired of all that useless noise around a subject which
have been discussed so many times.
