Describe the Problem

Why is the same json url that ethers always much slower than web3 when calling the same method. Whereas with websocket url, the speed of both is roughly the same. It was because of this that I switched from ethers to web3 in reluctance :(

Code Snippet

let Json_rpc_url = 'https://bsc-dataseed.binance.org';
const ethers = require('ethers');
const Web3 = require('web3');
let web3 = new Web3(new Web3.providers.HttpProvider(Json_rpc_url))
let provider = new ethers.providers.JsonRpcProvider(Json_rpc_url)

async function Web3JS() {
    console.time('web3');
    await web3.eth.getBlockNumber();
    console.timeEnd('web3');
    Web3JS();
};
async function ethersJS() {
    console.time('ethers');
    await provider.getBlockNumber();
    console.timeEnd('ethers');
    ethersJS();
};

It probably has to do with the consistency checking. If you are certain the URL won’t change networks, you should use the StaticJsonRpcProvider instead.

I tested again with StaticJsonRpcProvider method there is still no improvement. Here will test for 3 seconds for each method.

let Json_rpc_url = 'https://bsc-dataseed.binance.org';
const ethers = require('ethers');
const chalk = require('chalk');
const Web3 = require('web3');
let web3 = new Web3(new Web3.providers.HttpProvider(Json_rpc_url))
let provider = new ethers.providers.JsonRpcProvider(Json_rpc_url)
let providerST = new ethers.providers.StaticJsonRpcProvider(Json_rpc_url)

let stop;
function countS() {
    stop = false;
    setTimeout(function () { stop = true; }, 3000);
}

async function Web3JS() {
    console.time('');
    await web3.eth.getBlockNumber();
    console.timeEnd('');
    if (!stop) Web3JS();
};

async function ethersJ() {
    console.time('');
    await provider.getBlockNumber();
    console.timeEnd('');
    if (!stop) ethersJ();
    else {
        console.log(chalk.yellow('ethers : StaticJsonRpcProvider'));
        countS();
        ethersST();
    }
};

async function ethersST() {
    console.time('');
    await providerST.getBlockNumber();
    console.timeEnd('');
    if (!stop) ethersST();
    else {
        console.log(chalk.yellow('web3 : HttpProvider'));
        countS();
        Web3JS();
    }
};

console.log(chalk.yellow('ethers : JsonRpcProvider'));
countS();
ethersJ();
