BSC部署合约Gas费过高原因及支付拆分替代方案咨询

我已在BSC（币安智能链）上部署了如下合约，恳请各位指导该合约Gas费过高的原因，若有支付拆分的替代方案，也请不吝赐教。

pragma solidity ^0.8.0;

contract BNBTest {
    
    // Function to distribute BNB to multiple recipients
    function multisend(uint256[] memory amounts, address payable[] memory receivers) public payable {
        require(amounts.length == receivers.length, "Arrays must be of equal length");
        require(receivers.length > 0, "No receivers provided");
        require(receivers.length <= 2, "Maximum of 2 receivers allowed");
        
        uint256 totalAmount = amounts[0] + amounts[1];
        require(msg.value >= totalAmount, "Insufficient funds sent");

        receivers[0].transfer(amounts[0]);
        receivers[1].transfer(amounts[1]);
    }
}
