Re: High memory used by MySQL
Formula used ...
innodb_buffer_pool_size +
innodb_ft_total_cache_size + innodb_additional_mem_pool_size + innodb_log_buffer_size + query_cache_size + tmp_table_size + key_buffer_size + max_connections * ( thread_stack + max( max_allowed_packet, net_buffer_length ) + net_buffer_length + read_buffer_size + read_rnd_buffer_size + sort_buffer_size + join_buffer_size )
[corrected]
There's code under "Optimisation cheatsheet" at
https://www.artfulsoftware.com/infotree/mysqltips.php that produces most of the analysis I posted here.
The link to the MySQL mem use page didn't survive copy/paste, here it is:
