Re: MYSQL issues with query performance
Explain can't find a matching index for users, so i'd replace the users index (id,acceptsallworkgroups) starting with (competences_id,searching,acceptsallworkgroups)
and continue experimenting till the engine uses it.
(It's innodb so the pk id is automatically in the index).
Optimizer_switch settings:
show variables like 'optimizer_switch'\G
