[jira] [Created] (CASSANDRA-2578) stress performance is
artificially limited
stress performance is artificially limited
------------------------------------------
Key: CASSANDRA-2578
URL: https://issues.apache.org/jira/browse/CASSANDRA-2578
Project: Cassandra
Issue Type: Bug
Components: Tools
Affects Versions: 0.8 beta 1
Reporter: Brandon Williams
Assignee: Pavel Yaskevich
With stress I only get about 7k inserts/s against a single server, and the load and cpu usage from stress is higher than the server. Pystress gets 15-20k inserts/s against the same machine. Stress isn't cpu-limited however, so there must be something else holding it back.
