We've always taken the position that the amount of effort or size of delta/data is proportional to the size of the change. If you change all of a 9Gb working copy, then you should expect svn to take a good chunk of time and space. IOW, stop doing that :-) That said, even if we were desirous of "fixing" this(*), we would have a hard time doing it using threads. The Subversion client is pretty solidly single-threaded. We take no precautions for operation in a multi-threaded app. Cheers, -g (*) I'd be interested in what they are doing. Is this a use case we might see elsewhere? Or is this something silly they are doing, that would not be seen elsewhere?
