Flume NG Performance

According to Flume wiki[1], it has capable of achieving approx. 70,000 events/sec on a single machine (high-end level) at the time of the test with no data loss (300 bytes per event). If you can't imagine how big 70,000 events/sec is, see this "Tweets per second"[2].

Memorise these, and you could pass yourself off as an expert.
