Is this deduplication process implemented yet? I ask because if I repeatedly rename and re-upload a largish file the process takes pretty much exactly the same time to complete on each occasion, whereas I’d expect it to be quicker after the first time since the network will realise an identical chunk already exist and thus not bother to store it again. Perhaps the upload has to happen in full anyway before the network can make that decision? Or, alternatively, is it the encryption process rather than the uploading process that is the time-consuming bit?
