Hello, I think your approach is the fastest - you may set larger "window" size for generated delta when constructing SVNDeltaGenerator (default is 100K), but I tod not think it would affect performance. You may skip checksum computation if possible. Using latest version of SVNKit (1.7.11 or 1.8.0-beta) may improve performance as a lot of fixes and improvements has been made since version 1.3.5 of SVNKit.
