a) I hate to break it to you, but 6GB x 4 cores != 'high-end machine'.
It's pretty much middle of the road consumer level these days.
b) Hosting the client and Cassandra on the same node is a Bad Idea. It
will depend on what exactly the client will do, but in my experience it
won't work too
I was able to make Cassandra beat MySQL MyISAM (~10k inserts/s against 6k
inserts/s) using two physical machines (laptops) - one the client, and the
other one the server, with 50 inserting threads.
I don't know exactly why yet, but the high-level client that I was using to

Hello,
I've set up a testing evironment for Cassandra and MySQL, to compare both,
regarding *performance only*. And I must admit that I was expecting
Cassandra to beat MySQL. But I've not seen this happening up to now.
My application/use case is INSERT intensive, since I'm not updating
anything,
Howdy Gustavo,
One thing that jumped out at me is your having put two cassandra images on the
same box. There may be enough CPU and memory for the two images combined but
you may be seeing some other resource not being shared so nicely - network card
bandwidth, for example.
More generally,
In some sense 1 for one performance almost does not matter. Thou I bet
you can get Cassandra better (I remember old school ycsb white paper
benches against a sharded mysql).
One of the main bullet points of Cassandra is if you want to grow from 4
nodes, to 8 nodes, to 14 nodes, and so on,
Hello,
I have some experience in benchmarking Cassandra against Oracle and in
running on a VM cluster.
While the VM solution will work for many applications, it simply won't
cut it for all. In particular, I observed a large difference in insert
performance when I moved from VM to real
Edward (and Maxim),
I agree. I was just recalling previous performance bake-offs (for other
technologies, long time ago, galaxy far far away) in which the customer had put
together a mockup of the high throughput expected in production and wanted to
make a decision against that one set of
When I did some performance testing on Cassandra 0.7.6, I was getting
10,000 - 20,000 inserts per second on a *single *Cassandra node, on real
hardware (a consumer desktop PC with 4 GB RAM). Cassandra has got
substantially faster since then. I was inserting 1KB columns each on a new
row, if I
