Hi Christian,

Those queries are against PERFORMANCE_SCHEMA to gather the information for query analysis. They're not actually slow, but I'm guessing they trigger in the slow query log for you because they don't use indexes? Note, PERFORMANCE_SCHEMA tables are completely in-memory, aren't indexed and the queries themselves are sub-millisecond according to your slow query log entry....
