Yes, I think this is the "Linux factor". Seeing how long booting needs.=20
(Although I think that timeouts like the SCSI initialisation or non-existin=
g=20
DHCP servers need far more time than optimizing the filesystem could ever=20
give)

Yes, especially have a look at KDE.=20

I am currently thinking about multi-dimensional region search=20
(Sedgewick, "Algorithms in C", chapter 26 in the german edition), and how=20
something similar could be implemented on ReiserFS.
I am currently developing a Location-Based-Service application on top of my=
=20
IVI::DB (XML-ReiserFS database), and having 3-dimensional region searches i=
s=20
the primary service, my application has to provide.
At first, I wanted to implement Sedgewick's algorithm completely in RAM, bu=
t=20
now the requirements changed, and I have to do it in the filesystem, and I =
calculate with 30000 queries per minute.
Many greetings,
