figure out the current bottleneck for rhizome

[sebpiq]

Is it express, is it the websockets, is it the database ... ?

At the moment there is performance problems under heavier load : #107 , #95

• load testing of rhizome websockets and OSC
• load testing of the express server

Plenty of resources about that on the web ... and there's a stub here : https://github.com/sebpiq/rhizome/blob/master/benchmarks/round-trip.js

If websockets is bottleneck, we can decentralize them : #90
