I have two bootcharts.

Fedora's: http://img.wklej.org/images/77224fedora-bootchart.png
openSUSE's: http://img.wklej.org/images/50076opensuse-bootchart.png

Look at many differencies.

No.

In short what you got is:

openSUSE: 39 seconds 
Fedora: 41 seconds inspite of a very slow networking init

I cannot use NetworkManager, because Samba over DHCP doesn't work.
Also, NM for now doesn't use network config files (it's probably done in
SVN).

GDM is loaded earlier - starting feels much shorter.

Also, I've found reason of faster opengl drawing!
They include GARTSize option in Device section (for radeon). This makes
improvement of drawing, but makes me use XaaNoOffscreenPixmaps to avoid
shadow bug in Compiz. Also, without LIBGL_ALWAYS_INDIRECT Compiz wont start
(it's not a problem for me).

we had this in earilier releases, but this does not fix anything it
just hiddes the real issues.

benchmarks?

I don't have a radeon card so I can't comment on this.

where fedora or openSUSE ?
On fedora desktop-effekts takes care of this.

Are you sure? IIRC gdm-early-login never left the experimental stage.

I tend to disagree a small bit. It could be a net win if we'd use the
time while the user logs in (¹) for other things in the background
(loading things that we know will be used into the cache, start
non-crucial daemons, ....). It works well in Opensuse and the boot feels
faster (even if it's sometimes not that much faster if you measure it
with a stopwatch).

CU
knurd

(¹) currently afaics the computer mainly is waiting for the user to type
username and password (which can take 5 seconds or more -- depending on
how fast you type and if you are actually around when GDM shows up),
thus there are a lot of spare cycles that could be used for other things

yes but it was not on by default passing "early-login" to on the
kernel cmd was needed to enable it.

sure, but we somehow have to decide when to start gdm (ie to not break
nfs homedirs etc)

I'm not using desktop-effects.
I'm modifying /usr/bin/gnome-wm and using gnome-wm for starting WM.

So you're doing it wrong, and then complaining about the results?
Awesome.
