Yes, this is well-known. There's not much you can do.

Our collective experience is that 'svn co' is about 1.5x slower than
cvs on a linux client, and 3x slower on a win32 client.

However, svn does many other things faster than cvs.

Yes, svnserve is much faster than http. It's a stateful protocol,
rather than a stateless one.

Experience shows that FSFS is often a bit faster than BDB.

Why, because people are running 'svn checkout' every day? :-)

If so, you're doing something very odd. The normal usage is that you
check out a working copy once, then use it for months and months.

(And that's when you start seeing SVN speed advantages over CVS:
'diff' and 'status' require no network access at all. It takes only 3
seconds to create a branch or tag, regardless of the size of your tree.
  When updating and committing, diffs are sent in both directions.)
