I have tried a live cdrom with FreeBSD-5.3-RC produced by the livebsd
team,
http://www.livebsd.com/5_X/
and i must say i have been very much impressed. In particular no such
slowness as you mention. On the contrary, everything is very fast,
this live CD is basically in par with a linux Knoppix cdrom. Thanks
to the upgrading to KDE-3.3.0 windows appear really fast.

By trying it you can also discover the new drogonflybsd installer which,
in this CD, allows to install FreeBSD-5 to harddisk, directly from live
CD. One of the niceties of this installer is that you can pilot it from
a distant machine through a web browser, see:
