But after updating my xfce4 from cvs today I've found, that it's start time increased significantly and reached 36 sec (!!) on my Arch Linux box (AthlonXP1700 (1100MHz)/256Mb/7200rpm HDD). Then I've replaced xfce4-session from cvs of May 19 - the start time became 20 sec. The next step - cvs of April 22 - with the best result of 9 sec. (I measure the time xfce takes to start just after rebooting).

Somebody reported a similar problem on IRC recently. I think I know what 
causes this problem: You fire up 4 (or probably more) sessions clients, but 
they don't register properly with the session manager, and the session manager 
gives each client 8sec to register, so it waits this 8sec and then continues 
with the next client (4 * 8 + x = 36, where x is the overhead of starting the 
session manager, connecting to the Xserver, doing Autostart, etc.).

Since xfce4-session works fine for most of us, I think the problem is caused 
by libSM and/or libICE on your machine, or maybe your system configuration. 
Honestly I can't think of anything a user could mess up with, that'd cause 
such problems and wouldn't be detected the sanity check xfce4-session performs 
at startup, but if you find out, please let me know, so I can add it to the 
sanity check. You could start by sending every piece of information about your 
system regarding session management (Which OS? libSM/libICE version? etc.), 
maybe that helps tracking the problem.
