 * Hello,
 * Please try to run the following MySQL command to Identify long-running transactions:
 * `SHOW ENGINE INNODB STATUS;`
 * Also please check what size is for `innodb_log_file_size`
 * Because if `innodb_log_file_size` is too small, transactions cannot commit efficiently.
   
   As an alternative option, you may want to consider moving from MySQL 8.0 to MariaDB
   11.4. Because MariaDB offers enhanced query optimization and resource efficiency,
   making it ideal for high-traffic websites. More details about [MySQL vs MariaDB](https://olvy.net/blog/mariadb-vs-mysql-which-is-better-for-your-ecommerce-website/)
