OK, I thought JD encrypted a file entirely before sending it. Actually I was stupid to think that because even with more complex block cipher modes of operation JD can begin sending the file before finishing it's encryption. My bad. About the block level updates, that's my point exactly, there's no use in uploading differences for small files and when I edit big files I probably change most of the bits in the file so JD still has to send most of the new file. Thanks for your comment. Hello!

About the block level updates, that’s my point exactly, there’s no use in uploading differences for small files and when I edit big files I probably change most of the bits in the file so JD still has to send most of the new file.

Thanks for your comment.

It's true that JD uploads files one at a time, and that does cause lower throughput when uploading smaller files. That's something we'll be addressing in the near future. Regarding encryption, encryption is done in real-time as the file is uploaded and doesn't affect transfer speed at all. Block level updates are only done for large files (>1MB in size) so they don't affect small files at all. You’re right on at least one point, but a few of these aren’t accurate.
