If the clients are Windows, turn of 'Fast Indexing'. If you have an anti-virus installed on the Windows clients, make the checkout directory an exception location for on access scanning. Both of these will greatly decrease the time it takes to checkout from Subversion with a Windows client.
There are some performance enhancements in the 1.4.x release of Subversion. This helps on both the server and the clients. You might want to consider upgrading at least the clients.
