Quentin Conner commented on CASSANDRA-6410:
-------------------------------------------

+1
The gossip-intern.txt patch worked well, reducing server heap usage (casually measured) from
2 GB to 512 MB, when 500 node cluster was up.

> It looks to me that any given node will need ~2 MB of Java VM heap for each other node
in the ring.  This was observed with num_tokens=512 but still seems excessive.
