Right. I don't think we have measured the performance recently so I cannot comment off the top of my head, but at the same time I cannot think of a reason for why it would have changed.

The difference is that recycle does not require you to keep around (or be given) the untyped in order to then be able to perform the retype. Recycle is also a single syscall, and thus has better performance, than revoke + retype.

Oh yes, sorry, I know the difference in behaviour -- is the difference in performance in today's seL4 similar to what was outlined in the paper? I had it on my list of things to pay attention to based on those results.

Thanks,

Jeff
