PGA latency benchmark (alchemy vs moralis vs infura)

pga-latency-benchmark.ts

import { ethers, deployments, network } from "hardhat";

async function main() {
  const acct = (await ethers.provider.listAccounts())[0];
  const signer = (await ethers.getSigners())[0];

  const greeterAddress = (await deployments.get("Greeter")).address;
  const Greeter = await ethers.getContractFactory("Greeter");
  const greeter = Greeter.attach(greeterAddress);

  console.log("INFURA")
  console.log("feePerGas(gwei)   latency(ms)")
  for (let feePerGas = 2.5e9; feePerGas < 35e9; feePerGas = Math.ceil(feePerGas * 1.10)) {
    const now = Date.now()
    const txRequest = await greeter.setGreeting(
      "some new msg",
      {
        maxFeePerGas: feePerGas,
        maxPriorityFeePerGas: feePerGas,
        nonce: 22
      }
    );
    console.log(`   ${(feePerGas*1e-9).toFixed(3).padEnd(17, ' ')} ${Date.now() - now}`)
  }
}

main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});

This uses the hardhat default Greeter.sol contract
