any help on optimizing this query:

SELECT pp.function_name, pp.function_code, pp.function_uri, pp.time_out, h.*
FROM EPAGE_URI_TEST pp,
(SELECT pu.function_id, COUNT(1) numhits,
AVG(n.load_time) avgtime,
MAX(n.load_time) maxtime, MIN(n.load_time) mintime,
SUM(DECODE(SIGN(n.load_time - 10000), 1, 1, 0, 1, 0)) cnt_over10,
ROUND(100 * SUM(DECODE(SIGN(n.load_time - 10000), 1, 1, 0, 1, 0))/COUNT(1)) pct_over10,
SUM(DECODE(SIGN(n.load_time - 10000), -1, 1, 0)) cnt_under10,
SUM(DECODE(n.status_code, 204, 1, 0)) stat_204_cnt
FROM ltu_prod.LL_COMP_PAGE_NUGGET_HIT_TEST n, EPAGE_URI_TEST  pu
WHERE n.function_id = pu.function_id
AND n.timestamp > SYSDATE - 30
GROUP BY pu.function_id) h
WHERE pp.function_id = h.function_id ; -

Hi,

No, but if you provide an explain plan, execution statistics, and schema info (indexes, table structures, etc), we might be able to help.

Best regards.
