While running 9.04 and 9.10 (I have tried both) the kcryptd process uses just one core on an atom 330.
I'm seeing about 18-19MB/s throughput.

I doubt this is a bug, and instead I suspect that it needs to be submitted as a feature request. Clearly, encryption will be used more and more often, and there will continue to be more and more cpus with multiple cores.

Here are some others noticing the same issue:

Clearly, the maximum throughput is not the only issue since others above are complaining that they have issues with system responsiveness.

I realize the atom is not very efficient at this type of calculations, but a Q6600 still being limited to 80MB/s?!! Maybe a recompile would help, but I think a multithreaded implementation is needed. Where would I go to plead for/request this?
