No, i ment another thing.

Every query\stmt is executed multiple times (stmts are prepared only
once)
This statement
SELECT id, title, proto, lnk4, mdf FROM objects_hier oh WHERE owner =
?

works FASTER then query

SELECT id, title, proto, lnk4, mdf FROM objects_hier
WHERE owner = $owner_id

But this statement (i marked clob field)

SELECT id, title, proto, lnk4, mdf, xml_data <<<(clob) FROM
objects_hier oh WHERE owner = ?

works MUCH SLOWER then query

SELECT id, title, proto, lnk4, mdf, xml_data <<<(clob) FROM
objects_hier
WHERE owner = $owner_id

Every time ALL DATA is fetched from recordsets to script variables,
everything is made as it was described in DOC and is identical by
result except exec time

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Retrieving only a single recordset with a prepared 
statement is of course slower. Why do you use 
mysqli_stmt_store_result? The first recordset is already 
sent to client after mysqli_stmt_execute. 
 
Also there is no reproducible testcase in your bug report.

Sorry, some additional info:

Mysql 4.1.4 Gamma and clobs are not empty

Description:
------------
If result set has clob\blob fields, retrieving data is VERY slow.
Query "SELECT SQL_NO_CACHE id, xml_clob FROM some_table WHERE id = 1"
executes 1000 times for about 0.4 seconds on my server;

But this query rewriten with statement execs 20 time for 6(!)
seconds!!!

Every time i call:
exec, store result, fetch, free_result


P.S. SQL_NO_CACHE is used for clean noncached result times

Expected result:
----------------
STMT performance higher then normal query performance
