Hi Alonso, I followed your hints and the startup time of KDE4 slightly improved. Thanks. Then I copied the /usr/local from the USB to the SSD of the EeePC and mounted it from there during boot. This has nearly no effect on the start time of KDE4. What really helped was copying the HOME of the user of KDE4 to the SSD. There seems to be a lot of disk i/o in the mysql database and other files on startup. I know have to learn how to manage KDE4 because it differs a lot from KDE3.

[kde-freebsd] KDE4 processes (10-CURRENT r255948, ports r328930), slimm down for netbook?
Hello, I have prepared a bootable USB key with 10-CURRENT and KDE4 from ports; it boots fine in my little EeePC 900, takes around 90 secs until login: and KDE4 starts fine too, takes around 240 secs from startx to be able to start an xterm application in KDE4 desktop; i.e. it works, even from such a slow USB key which has a read performance of 1 to 17 MByte per sec, depending of the blocksize 512 or 8m; All this is only a proof of concept to prepare such USB key to boot from and reinstall from it the system on my EeePC netbook which runs at the moment r235646 with KDE3 (which is now dropped from our ports tree). It seems that KDE4 launches a lot of applications or services which I will not need, for example all these akonadi_maildir processes (see attached ps -ax output; for what they are good for? Any hints to slimm down the KDE4 on a minimum for small netbooks?

The box I'm writing this email from uses an USB key which is even slower than yours as boot/root/usr.local (i.e. the things are don't need to be backup-ed), in order to be able to perform a full bootup even if the ZRAID fails to come online, and I can launch have konsole/konqueror in like 60 seconds from POST. Dual Xeon E5-2620 and enough memory though. You can configure some of the kde background activies using systemsettings from kde4-workspace.
