When using svnsync, it can take as long as it needs to because you have total control over the switchover and can do it with minimal downtime. But the actual time to do svnsync is generally longer than dump/load. My point was only that you do not use svnsync because it is faster, you do it because you can better control and minimize the downtime. -- Thanks Mark Phippard http://markphip.blogspot.com/
