After admining on both Linux and Windows for several years, to me there
is still a convenience factor for Linux. Packages are a "<pkgmanager>
install" away, and tools that the scripts are looking for exist by
default (e.g. don't need to go find gnu diff for win32...)

Sadly, this will have little performance effect on your *svn*
performance[1] because no mater what svn does NTFS is still slow to open
many small files. It *will* make it feasible to use Windows Explorer to
browse your FSFS repo though.

A Linux file system will still give FSFS a 2-3X performance boost in my
tests. I suppose BDB is not affected very much, but haven't personally
used it in a long time.
