No, simply bootstrapping. Basically, as soon as the new node starts joining
load average spikes like x10
And it's not like the load comes from streaming (judging from what I see in
visualvm), it's writes that start taking much more cpu, mostly for nio socket
select.

Dear all,
So, here is our setup so far:
- Ubuntu 12.04
- Cassandra 2.0.10, JDK 1.7.0_65-b17
- 6 nodes (EC2 c3.8xlarge/ 32 cores/60GB RAM, EBS disks for data,
ephemeral SSD for commit logs etc)
- pretty heavy write load - 100Ks/second
- RF=2, one dc, 2 racks
- everything works just fine
