help me make solana transaction faster
`async sendSplTransaction(wallet, {to, value, mintAddress, decimals, fee}) {
const recipientPubKey = new PublicKey(to);
const mintPubKey = new PublicKey(mintAddress);
const bigValue = this.convertToBigInt(value, decimals);
const recentBlockhash = await this.provider.connection.getLatestBlockhash();
let currentBlockheight = await this.provider.connection.getBlockHeight();
const { blockhash } = await this.provider.connection.getLatestBlockhash();
const MAX_RETRIES = 3;
let retryCount = 0;

    while (retryCount  setTimeout(resolve, delay));
            } else {
                return { success: false, data: null, error: error.message };
            }
        }
    }

    return { success: false, data: null, error: 'Transaction retries exhausted.' };
}`
