I have been using Linux since 1993. I installed the first version of Slackware on a 16MB 386sx-25. Since then I have been using it almost exclusively on one or more of my PCs. So I consider myself as a bit of an expert. I have been using computers since 1982 mostly PCs, but also VAX mainframes and SPARC systems. Operating systems (and GUIs) I have been using include CP/M, DOS, Windows from Version 2 to XP, Geos, Beos, SCO Unix, Solaris, OS/2 and quite a few Linux Distros.
It does seem like an extortionate amount of time for an Office suite to load up. However, there are a few variables to take into consideration.
1: Did Beetman optimise his system
2: Did Beetman select the quickest filesystem when installing
3: What else is he running as processes
4: Which version of OOo was running , 1.0 being rally slow, 1.1 fast
Your example.... 2 seconds to load Word without preloading. This does look impressive, however, You cannot turn OFF preloading for any Microsoft app. The shared libraries are already loaded by the time Windows starts. They also use PRELINKING.
If you study the Linux scene much, you will understand that the authors try to get the software working properly before they start to optimise for speed.
Try KDE 3.1 in comparison to KDE 3.2 and try OpenOffice 1.1 compared to OpenOffice 1.0
Also try formatting your system in reiserfs instead of EXT3, which Mandrake defaults to, and if using reiserfs, make sure you have notail and noatime options added to fstab.
