Subject: Benchmarking Cassandra 0.6.5 with YCSB client ... drags to a halt

Hi,

I'm currently executing some benchmarks against 0.6.5, which i plan to
compare against 0.7-beta1, using the YCSB client

I'm experiencing some strange behaviour when running a small 2 nodes cluster
using OrderPreservingPartitioner. Does anybody have any experience on using
the client to generate load?

It's the first benchmark that i try so i'm probably doing something dumb.

A detailed post with screenshots of the VM and CPU history can be seen in
this post.

I would very much appreciate your help since i'm doing this benchmarks as
part of my master's dissertation

A previous official benchmark is documented here
http://research.yahoo.com/files/ycsb-v4.pdf

Thanks!

Fernando Racca
