14 Hi,
15 Nothing technical that's undisclosed. My original reason was not
16 knowing what rsync did in the case of errors I simply didn't want to
17 start over on such a big file. I figured there was little to lose by
18 stitching it back together are the other end and I could always figure
19 out exactly what file had failed.

21 That said I don't think there's much difference in the speed. In my
22 case (and I think others will have a similar case) my uploads speeds
23 are far lower than download. I get about 8MB/S download but only about
24 250KB/S upload. It's that low speed that's dominating everything else.
25 When I first tried transferring the big file the intermediate speeds
26 rsync was reporting were very similar.
