Subject RE: Start Up Time

If the versioning initialisation performance is a known issue that requires
attention, has anyone had any thoughts on how to improve this?

I have noticed the poor performance when adding several thousand nodes to
version control and was wanting to come to a quick solution.  At the moment
we are running the repository on NTFS (which I know does help things) but
after moving to linux and ext3 the performance didn't really improve so I am
assuming there is something needing to be greatly optimized in the code
above at the PM level.

I will be looking into this in more detail next week, but any pointers would
be welcome.
