Re: Performance regression with reverse merge

So here are my timings from Linux using 1.6.0 RC2. I'll try again
with 1.5.6 in a bit. My home folder is on a NetApp, so the svn up
command is just to get a timing on walking and locking the WC.

$ time svn up -r15533 --ignore-externals TSVN
At revision 15533.

I also tested from a Windows system running RC2. For this test, I
only checked out the "src" folder and did the merge relative to it.
Here are those timings. The Windows tests got to the merge
notifications in a similar timeframe to Linux but then had a really
long delay before finishing.

I agree this seems slower than it ought to be.
