FWIW, I get the same thing, and most of my big updates are with the command-line 1.5.2 client, so this probably isn't a TSVN issue. And as far as I know, I have the latest drivers.

Personally I think Subversion is doing a little network and probably a ton of disk I/O, maybe determining the revisions for the thousands of directories in my WC. So maybe this problem will go away in Svn 1.7.0 but I wouldn't expect any better right now.

Supporting notes: Running svn update a second time is much faster, even when only a small amount of data came across the first time. I think this is because the OS has cached a lot of info by this point. Also, operations like svn commit or cleanup take similarly long if it's the first time, or if it's been a long time since I did them. The common thread on these, as far as I know, is that they all have to walk the entirety of your WC.
