Hi Julian,

To get a rough idea I ran upgrade on some bigger WCs this weekend:

WC for | Files | Dirs | Size on Disk | Elapsed
Upgrade Time
----------------------------------------------------------------------
^/subversion/tags/1.6.7[1] | 3,214 | 449 | 69.3 MB | 00:02:04
----------------------------------------------------------------------
^/subversion/tags/ebcdic[2] | 14,703 | 1,826 | 313.0 MB | 00:11:44
                            | x 4.57 | x4.07 | x 4.52 | x 5.65
----------------------------------------------------------------------
^/subversion/branches[2] | 91,534 | 9,720 | 2.16 GB | 03:46:10
                            | x28.47 | x21.64| x88.15 | x108.70
----------------------------------------------------------------------

So upgrade performance is roughly linear with WC size. Why upgrade is
so slow on my Windows box as compared to Philip's linux box are
another matter, one which I'll touch on elsewhere in this thread in a
few minutes.
