New DSS benchmark available (or nearly).

Over the last few days I've been putting together swingbench's first DSS benchmark. It uses datagenerator to create the schema and then a new config file to generate the load. The only reason I haven't posted it yet is that our cluster is currently in pieces and is slowly being put back together so I'haven't had a chance to test it on a large scale machine. Im certain of a few things. It should eat I/O and CPU. I haven't included any materialized views to improve perfomance simply because in the past I've been asked for a benchmark to test the I/O sub system, I think this is it. It currently needs a little work to get it to scale to large sizes but I'll post instructions. The ultimate aim is to deliver three sizes 100GB, 500GB and 1TB. There's no reason why they couldn't be bigger its just that I'll lack the resource to test it. If you'd like to give it a spin drop me a line and I'll send you the code. Regardless I hope to post the code by the end of the week.
