Cronos Stress Test

This test cause is used to tress test the mempool, sending token transfer tx and contract tx and watch the mempool status and block mined time.

start

1. init cronos: sh init_cronos.sh
2. start cronosd: pystarport start --data ./cronos_data
3. start the stress test: python3 main.py

test result

mempool will full when the pending transactions up to nearly 5000, send tx will get error message: mempool is full what ever how many pending transaction is, the block mined time is always 5s or 6s which is same as set by timeout_commit in genesis.
