This screenshot shows that few minutes after having opened the desktop
session, after startup application have initialized, ubuntuone-
syncdaemon is still hashing and consumes lot of resources.

The size of files in my Ubuntu One account is about 300M each, which is
a possible explanation for such a long time spent in hashing. However I
tried this command to get a hash value of one of these files on the same
computer:

$ time sha1sum 300.mega.bytes.file  
9ee2e5689ece78a5644aa357597473cb127a7e4c  300.mega.bytes.file

real    0m12.493s
user    0m3.976s
sys     0m8.189s

And I get a result in 12s, which makes me think that the right solution
for ubuntuone-syncdaemon could be not only executing with a higher nice
value, but also using a less time consuming hashing algorithm.

Cheers.
