The problem here is twofold:

 1. 'svn status' isn't streamy. It walks the entire working copy
    before printing anything. We have an issue filed on this.

 2. win32 disk i/o is much *much* slower than unix. We're not sure
     if it's just win32 itself, or the way in which APR's disk API
     uses win32 calls.

What you're seeing is a well known thing: slow disk on win32.

'svn st -v' doesn't connect to the network. :-)
