Re: reduce number of administrative files

it was both, samba and real nt server.

people moved from ms visual source safe and tried to store their
working copy as they used to on the network drives. it was so slow,
that we just exculded it from a "valid application scenario".

now we have the wc on the loca drives, but the working copy size is
increasing and it will have soon a size which again gives us a slow
speed combined with a blocked disk. status now is that "svn up"
blocks the computer for 2 minutes, increasing with working copy size.

and svn client is the only program we use here which is able to block
our computers by just running it (except stress test programs).

but it would be anyway interesting to hear your tuning experiences.
