When I drag&drop a large file (For example a 650MB iso file)
to Wuala then the encryption should use all cpu's/cores instead
of a single one.


- In the first step wuala makes a copy to it's internal temp location
- In the second step the copy of the file is encrypted

The encryption of a 650MB iso file takes about 20-30 seconds on my 
dualcore system.

What can be seen, is that during encryption there is little disk activity
but the CPU load cummulated over all cores/cpu's is only 50%.

So in fact the encryption task is done on a single core or cpu.

Since there are more and more multicore systems available
it would be good to use them.


I can think that on decryption probably the very same
happens.
