spreading partitions over multiple drivers

[Geert Hendrickx]

Hi tuners, 

apart from using RAID, what would be the best way to spread load over
multiple drives?  

I was thinking about a partition layout like this: 
disk1:	/, swap, /var, /usr, /usr/src, /usr/ports
disk2:  /tmp, swap, /home, /var/www, /usr/obj (+ ports-workdirs)

And would it make sense (if the disks are large enough) to split /usr
into seperate /usr, /usr/local, /usr/X11R6, etc partitions to reduce
fragmentation?
