I used RapidSVN which is quite annoying when connection speed is not enough fast or simple you must wait few seconds the server to respond.
I would recommend using SVNFlash Standalone deployed in your Server. It's the best tool at the present to explore Subversion repositories.
At the client side I would recommend using the command line and explore changes using Firefox to access SVNFlash on the server.
SVNFlash is an amazing web application to explore Subversion repositories in particular when repositories are big an changes are difficult to track.
If you used TortoiseSVN (Windows tool) then you will not miss it anymore in Linux
Have a look at http://www.svnflash.com (Standalone version)
