Is it ok for MySQL to always use 18-25% of Memory (I have 2 GB Ram)? I have MySQL 8 in my Server with Ram of 2GB. And MySQL is always using 18-25% of Ram even when everything is off. Is it normal? If not then plz let me know how to debug it.
It's normal. Memory usage is determined by various configuration parameters, some of which are shared (e.g. innodb_buffer_pool_size), while others are per thread.
