Yikes!
And I was wondering why nobody mentioned the slow merges before :)

I stepped through the svn code for mergin a little bit. Most commands
only connect once and then use that connection. However, the merge
command does multiple 'connect()' calls, which I think is one reason why
merging is so slow.
I'm now doing some tests with svn:// - it seems that having IPv6 enabled
*has* some impact on speed. Currently rebuilding without IPv6 support
for more tests with svn://
