Hi I am quite new to RIAK-*. I have setup riak cs on a single server (for evaluation purposes) with adequate RAM, CPU and high performance storage. I am using Cosbench to benchmark RIAK-CS using the S3 proxy connection. Cosbench is also running on the same server (the reasons being I wanted to eliminate the effect of network on performance).
I have tried different workloads (100% reads, 80:20 read write mix, number of objects (20-20000), size of objects (4K-64K)). My observation has been that I have not managed to push the throughput to beyond 2.5Kops - the best case being 100% reads and about 128 objects and 128 cosbench worker threads. With 20% writes the number comes down to less than 1000. The CPU is largely idle, plenty of RAM left (order of GB). Storage is capable of 300K+ IOPS but hardly utilised. Coming to my question: does this represent the limit of performance of a *single* riak-cs node. I notice that the average response time is in the order of 60ms. Lastly, has anyone compared S3 with RIAK-CS?
