Robert Stupp updated CASSANDRA-11972:
-------------------------------------
    Status: Patch Available  (was: In Progress)

Yea - maybe. Unsure after I've sorted out all the other stuff. Had the patch handy anyway.
Wouldn't mind if it's considered not worth to commit.

> Replacing the object tree/references in {{Frame.Header}} with {{byte[9]}} saves a couple
of object allocations. Also, not allocating the 9 bytes for the header off-heap is less expensive.
