Test script: --------------- $mysqli = new \Mysqli(".", "user", "pw", "db", null, "\\\\.\\pipe\\MySQL"); $s = microtime(true); $result = $mysqli->query("SELECT * FROM user"); var_dump($result); var_dump(microtime(true) - $s); Expected result: ---------------- Fast "query result" like with libmysql (~8ms) Actual result: -------------- Very slow (100ms) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69843&edit=1
