Description From Mathieu Lacage 2007-11-22 04:42:17 EDT

This is the case since we switched to Ptr<Packet>. It is due to two things:
  - Ref/Unref are not inlined
  - Packet needs a free list

So, we need to fix both issues and verify that the new free list does not
interact badly with the other free lists in Buffer, PacketMetadata, and, Tags.

------- Comment #1 From Mathieu Lacage 2009-11-23 08:28:01 EDT -------

ref/unref are not inlined anymore.

We still need to go back seriously to the packet code and try to figure out if
a packet free list would help. Marking as enhancement.
