calculate mysql memory

MySQL & MariaDB Other MySQL® Questions

At startup, mysql will use some memory.

Some of the memory is pre-allocated for “key_buffer” and “innodb_buffer_pool_size” ( and other things ).

Is it possible to determine how much memory is used for the server itself without the pre-allocation part ?

Thanks in advance.
