It only steals entries which have not been recently used. I just asked whether this was possible in a previous email, but you must have missed it. I am seeing a lot of memory management stuff in profiles, so I think recycling routing cache entries (if only when the table is full and the garbage collector would otherwise need to run) would be very helpful. Is it possible to get a good guess of what cache entry to recycle without walking for a while or without some kind of LRU? > The big problem area on SMP is fib_validate_source.
