I've reversed the way the timings are printed -- so that the "most interesting" stuff is at the top. The detail increases the further you read down.
Across the board these results suggest a tendency for faster operation in
trunk, compared against 1.7.x. 'svn copy' is the only operation with a
slight speed dip (~ 4% slower in trunk).
Trunk's "svn info" shows a near 10-fold speed increase (88% less runtime!)
[1a], and 20% less runtime for 'svn merge' [2a], both in WCs with evenly
spread dirs and files.
Switch, update and commit aren't too bad either.
Most perf improvement is in WCs with evenly spread dirs and files, compare
[1a] [2a] with [1b] [1c] [2b] [2c].
Some more legend:
5x5: 5 dirs and files per dir, 5 levels deep [1a] [2a]
100x1: 100 nested dirs [1b] [2b]
1x100: 100 files in a single dir [1c] [2c]
All this is ra_local only, on GNU/linux.
