I use 2 Clients with 32 Threads for inserting and the Cluster has 2 Nodes.
The hardware specs for clients and cluster nodes are identical:
Dell PowerEdge C62202 with
- 2 Intel Xeon E5-2609 (each 4 Cores)
- 32 GB RAM
- 4 x 1 TB SATA 7.2 k
- Ubuntu 12.04 LTS
Cluster Nodes only:
- sysctl vm.swappiness=0
- echo never > /sys/kernel/mm/transparent_hugepage/defrag\
- /sys/kernel/mm/transparent_hugepage/enabled\
- Oracle JDK 1.7.0_72-b14
Client only:
- OpenJDK 1.6.0_32

Description
At the moment I'm doing some tests with couchbase 3.0.1 community edition and the java sdk 2.0.1. In full metadata ejection mode the performance drops after approximately 100 million inserts. In contrast, the value ejection mode performs 200 million inserts without problems.
My code is based on the thumbtack ycsb version (https://github.com/thumbtack-technology/ycsb), but i added new DB adapter (based on java sdk 2.0.1).
