One could try using/making a UFS partition.  Mac OS X supports it (it's=20=

the file system that NeXTStep/OpenStep for Mach used), but some Carbon=20=

apps and all Classic apps have problems dealing with it.  I don't know=20=

if Apple still recommends installing Mac OS X Server on a UFS partition=20=

or not.

I thought the startup time had to do with XML processing initially. =20
Maybe it has to do with all of the little files and directories that=20
have to be dealt with now?  *shrug*.

In any case, this is an area of the OS that is expected to be improved=20=

(perhaps dramatically) with the next major release of OS X.

This paper [1] may help.  It describes the challenges of integrating=20
the Unix and Mac OS environments, and touches on file system issues. =20
It may provide some clue to HFS+ issues.
