Actually, Subversion is a bit more intelligent about it, attempting to use

Even that can be slow if there are lots of files involved.  Note that some filesystems 
have particularly bad performance if there are lots of files in a single directory, as 
well.  This is especially true of NFS.  In one extreme example, I've seen a simple 
"ls" take tens of minutes to produce any output in an NFS-mounted directory 
with ~1,000,000 files.

But to be fair, note that ls sorts its output, so it can't output anything until it has read everything.
