Actually those file and folder counts were done on my working copy, so
maybe that's not the best measure of Repository size and numbers.
Anyone know a fast way to get those statistics from the server side?

What you say about file-folder ratio is interesting, because the .svn
folders seem to have a lot of sub-folders that remain empty most of
the time. Has a flat-file type WC cache alternative been considered? I
think Mercury uses something like that -- one big WC status file per
project, and I hear they have some claim to good speed on all
platforms. I admit I haven't done a full evaluation myself, because it
lacks folder tracking and rename support.
