Could be right. Checkouts are slower in Subversion than CVS. This is  
unavoidable because Subversion does a lot more at checkout time than  
CVS does. However, checkout is not an operation users are expected to  
perform often. Users are expected to check out once, then use that  
working copy for a long time. Most operations other than checkout  
should be faster in Subversion than in CVS.
