Actually I believe that a GC will cause little paging -- the memory that a GC touches is by definition dirty, so is never a candidate to be swapped out (since we don't do swapping). The only paging that could happen is due to pages with code that has not been used for a long time (maybe finalizers?), since those are clean mmapped pages so can be dropped from memory if needed. The bigger impact would be on CPU caches, which on these devices are quite small. -- Dianne Hackborn Android framework engineer [email protected] Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.
