Mysql 5.1 to 5.5.1.18 Upgrade Poor Performance
Posted by: Thomas Frederiksen ()

We recently upgraded to 5.5.1.18 and have noticed massive performance degradation with any query that has a dependent or correlated subquery. None of the INI settings changed other than renaming default_character_set to character-set-server.

I have turned query cache off now, but haven't had the opportunity to bounce the server.

Please see the query below as an example. Original time was around 3 minutes and it never finishes now.
SELECT
    NULL,
    ce.contract_esiid_id,
    c.contract_execution_date AS 'EventDate',
    IF(c.is_renewal = 1, 2, 1) AS 'type',
    cu.state,
    IF(ch.actual_kwh IS NOT NULL, IF(e.commodity='E', ch.actual_kwh, fn_gas_to_thm((SELECT h.units FROM tblraw_hud_data h WHERE h.gkey=ce.gkey ORDER BY start_date DESC LIMIT 1), ch.actual_kwh, e.gkey, (SELECT h.sender_transaction_id FROM tblraw_hud_data h WHERE h.gkey=ce.gkey ORDER BY start_date DESC LIMIT 1)) ), 0 ) AS 'hud',
    e.commodity
FROM tblcontract_esiids ce
    INNER JOIN tblesiids e
      ON e.gkey = ce.gkey
    INNER JOIN tblcontracts c
      ON c.contract_id = ce.contract_id
        AND c.recstatus = 1
    INNER JOIN tblcustomer cu
      ON cu.customer_number = c.customer_number
    LEFT JOIN tblcalendarized_hud_totals ch
      ON ch.gkey = ce.gkey
WHERE ce.recstatus = 1
      AND ce.void = 0
GROUP BY ce.contract_esiid_id
ORDER BY NULL
