OK, I finisher next analyze with performance_scheme with query :
SELECT EVENT_ID, TRUNCATE( TIMER_WAIT /1000000000000, 6 ) AS Duration, SQL_TEXT
FROM performance_schema.events_statements_history_long
ORDER BY Duration DESC
LIMIT 0 , 30

and everything looks in timeout limit.
Soo it looks like PHP PDO is problem.
