This test was done to measure the SC ERC20 token transfers, SC ERC721 token minting and EOA to EOA transactions functionality with heavy loads and speed of the transactions on the nodes with higher hardware resources.
The goal was to check if everything is working as expected during heavy loads. That was also the reason we’ve introduced gas metrics in the loadbot output, which show us if the blocks are filled with transactions properly.
All transactions were sent to the single node via GRPC API, and the receipts were received via JSON-RPC API. After all transactions were done, gas information was read from each block, using the eth_getBlockByNumber JSON-RPC method.
Our aim was to strive to reach a maximum possible TPS on the hardware resources available. To acheive this, we've modified the block gas limit and block time parameters, to give us the best possible tps results and keep the system integrity and stability.
Production Environments
When configuring a production environment, you need to be carefull if you're trying to acheive high performance of the chain. If block gas limit parameter is set to a high value, block time is set to 1s, and there is a high transaction load on a single node, that node will consume a lot ( if not all available ) RAM and can cause server crash. Use the loadbot to test everything thoroughly, monitor the system resource utilization and set your configuration parameters accordingly.
