Why does my computer (quad core, 4gb ram) slow to a grinding halt when ubuntuone is syncing!!! I'm on 11.04 and getting really fed up with it... I can't do anything when it syncs!

Easy solution: install Dropbox, and uninstall Ubuntu One. ;-) – Jason Silver Apr 10 '13 at 23:46

If this is the initial sync and you have many thousands of files, there is a known bug in Ubuntu One which causes high CPU usage. It should, after a while, drop to normal levels.

However, if you stop it before it's finished, it will start again.

A good page for issues with Ubuntu One is the Bugs Wiki which answers most problems.

It seems to do it after a while and I only have about 500 files in my sync folder – chris Oct 24 '11 at 12:20
