Perhaps I wasn't clear, the second set of runs where with a local
working copy instead of an nfs mounted working copy.

What are your NFS mount options?

        LOL! I love the env variable.
        
        Here is some similar data for a local working copy. These are
all run with the env variable set. Again, svn rm is significantly
slower than all other operations.
        
        svn rm <file> 0.35s
        svn st <file> 0.105s
        svn blame 0.041s
        svn unlock 0.056s
        svn lock 0.053s
        svn log 0.036s
        svn info 0.014s

But look how much it improved compared to how much the others improved?

svn rm <file> 7s
svn add <file> 0.126s
svn st <file> 2s
svn blame <file> 0.2s
svn lock <file> 0.12s
svn unlock <file> 0.103s
svn log <file> 0.089s
svn revert <file> 0.133s
svn info <file> 0.074s

Many of these commands are not even impacted by that variable. That
said, I do not get how this envvar can shave 7 seconds off the operation
when it usually only sleeps for a second.
