Comment 12 for bug 396650

This bug is not fixed, I just tested Ubuntu 10.04, updated all packages, and still the ubuntu one sync process syncs very slowly.

Sometimes it delays 30 seconds/file. I am trying to upload 136MB, 6049 files. It is uploading since 3 hours, and all it uploaded are the filenames (not all of them either).

I looked at its log ~.cache/ubuntuone/log/syncdaemon.log, here's a sample:
2010-03-25 22:19:34,474 - ubuntuone.SyncDaemon.ActionQueue - DEBUG - MakeFile
                  share:'' node:marker:2eb
7f495-da39-4a06-b839-59031ee8ce43 MakeFile(marker='marker:2eb7f495-da39-4a06-b83
9-59031ee8ce43', parent_id="'e93bee79-b3a2-480d-aec1-8047cd8852b3'", share_id="'
'", name="u'split.clam-mew.exeaa'") running
2010-03-25 22:20:03,822 - ubuntuone.SyncDaemon.ActionQueue - DEBUG - MakeFile
                  share:'' node:marker:2eb
7f495-da39-4a06-b839-59031ee8ce43 MakeFile(marker='marker:2eb7f495-da39-4a06-b83
9-59031ee8ce43', parent_id="'e93bee79-b3a2-480d-aec1-8047cd8852b3'", share_id="'
'", name="u'split.clam-mew.exeaa'") success

If creating new filenames is this slow, then you should batch upload the filenames.
Or even better, use a tried and tested technology like rsync, or FTP, instead of reinventing the wheel, and creating an upload sync that is slower than all other technologies that currently exist!
