StreamInsight currently has no support for clustering. The 5000 events/second is an
estimate only and your actual throughput will depend on a lot of factors, including complexity of analytics as well as CPU and memory speed. The Premium Edition of StreamInsight would, for your needs, probably be a better solution; it'll handle
10's of thousands to 100's of thousands events per second. This is included with the Enterprise Edition of Sql Server and, from a cost perspective, would still wind up being less expensive than doing multiple Standard licenses on multiple machines.
