Public bug reported:
Binary package hint: ubuntuone-client
Jaunty 64bit.
UbuntuOne client: 0.93.1+r191
I'm trying out UO as a replacement for Dropbox in part; I've been
syncing dotfiles and other sorts of config that I want to keep parallel
on several Ubuntu boxes that I use. UO is attractive to me in its focus
on Ubuntu (permissions, prolly better support for unix in general) and
I'd like to have a good reason to give Canonical some money.
Last night I put about 70M worth of files in, the bulk of which is files
from the Firefox Scrapbook plugin. This plugin downloads web pages
recursively, including attached media files, to keep an archive. This
means that there are many very small files.
UO started sync'ing the files, but very slowly. There were 6000+ to
sync, which is a lot. After a few hours, it was about 1000 files in, so
I left the machine overnight. This is a very fast machine with 4G of
RAM, and a decent broadband connection (¾Mb upload connection). It was
taking about 5 seconds per file, according to the simple status update
on mouse-click (Updating xxxx of yyyy). No other significant network
activity was occurring.
This morning, the sync had simply stopped. I don't know how far it got;
there were no messages. The web client said that I had about 19Mb of
files; not 70Mb. There were no error messages anywhere.
I put a tiny txt file into the UO folder to get it started sync'ing
again, and UO crashed. Minutes later, apport tried to send a report...
which ate 2.43G of RAM and of course failed, getting a 500 error from
the Launchpad server.
I logged out, logged back in, and UO said "up to date". About 5 minutes
later (and some furious hard-drive thrashing), it started sending files
again... 5s per file or more.
I'm not sure which particular component of this setup is the problem,
which is why I'm being so verbose in this report; sorry. It simply
should not take 10hours (well, maybe more!) to send 70M on a ¾Mb
connection. Dropbox works quickly and reliably; I set it and forget it,
so it's not a matter of net connection or congestion.
