We've been doing some benchmarks with Elasticsearch on the 5-node PicoCluster. We were able to push 1,000,000 tweets and 3495.1316MB in just under 9 hours. The tweets are small, around 1KB each, but have a lot of fields and are pretty complicated. That's pretty good considering that the SD cards are not very good a small reads and writes.
