Hi… Current user of BTSync here,
I was planning on moving over to this promising FOSS project until I read this discouraging post linked below (notice the first response by Calmh after OP). Please quickly read the first 2 posts at least before continuing here.
Ok so my question is this. Given the known behavior in that linked post, how is this program beneficial (for large file transfers) over any other plain old sync program, like FreeFileSync? Under realistic network loads and behaviours, if computer A introduces a large file to the “mesh”, all clients will have just about 80-90% of the file before the fastest reciever will be able to advertise that it ALSO has that file and can finally start sharing the upload load with the original sender. Doesn’t this completely negate the point of a p2p mesh and all the added complexity that making a program and protocol for it brings? No offence but we might as well be making a plain jane syning program here instead of a BitTorrent like program/protocol that allows swarm uploading/downloading for much faster syncing.
I understand about arranging the mesh into more of a tree instead, or perhaps just using zip to span the large file into many smaller ones but this misses the point. TBH, those remedies sound like the user having to unnecessarily add complexity themselves just to fix the shortcomings of the current design in the first place no?
Please let me know if I an missing something big here. Also, while constructive criticism is welcome, please don’t attack me. I’m not trying to tear down this program/project as it seems to have a great start. I just want to know if I am on the right track here in the questions I am asking.
Also can anything be done with the design to make it more like the BitTorrent protocol where, when a large file is added, peers can immediately start uploading pieces they have recieved as soon as those pieces are complete, not just the entire contents of the file? I might even consider trying to help develop it a tweak like that if it isn’t too hard and or completely changes the way the program/protocol works.
Here’s to hoping for a truly robust and superior FOSS product in the years down the road.
