I am trying to perform a heavy load and scalability tests on a smart contract. However, the test takes a lot of time because only 1 transaction is added per block. I read that this might be due to gasLimit of the block but currently my blocks have a limit of 3877440195466 gas and the transaction that is processed take s "txs=1 gas=36544". I am wondering how can I fix that and also if there is a way to change my mining code so that more transactions are added per block?

  • What is your geth command line? Is your network PoA or PoW? What is your genesis file? A geth blockchain can be configured to generate blocks at a fixed interval of time instead of mining immediately.

    @Ismael It is a PoW chain. I believe I found what the problem is but I am not sure how to fix it. Basically, I am testing an ERC20 token and I am trying to perform 500 transactions in a truffle test and measure the time that it would take for all of them to be processed. I was using 'await contract.transfer(..)' for each transaction in order to measure how much time it took for the transaction to be deployed but await causes transactions to be processed 1 by 1. When I removed it , the blocks included multiple transactions but I dont know how to measure the execution time in this case

    Is it possible you are waiting for transaction confirmation before emitting the next transaction? That would indeed result in one transaction per block.

  • @Rob Yeah I believe that's the problem. The problem is that I am not sure how I can get confirmation for transactions without await so that I can measure the time it takes for all of them to be processed

  • You don't have to wait for confirmation to send the next one, although you should be prepared to deal with the failure case. This might be helpful (I like #2) or maybe skipping ahead too fast. ethereum.stackexchange.com/questions/39790/…
