Summary

This test was done after the TxPool refactor which significantly improved performance (released in v0.2.0).

The goal was to setup a large network consisting of 30 actively participating validators in order to properly stress test the consensus and TxPool transaction gossiping as all transactions were sent to a single node's JSON-RPC.

Our aim was not to strive to reach a maximum possible TPS, as the network size negatively impacts the performance, and since block gas limit & block time are set to sane values that don't consume much system resources, and would allow this to run on commodity hardware.
