มีหลาย Query ในหนึ่งหน้า ทำให้หน้าเว็บช้า แก้ยังไงดีครับ

$sql ="select page_name, post_message, post_picture, page_category  FROM tbl_page INNER JOIN tbl_post ON tbl_page.page_id = tbl_post.post_page WHERE DATE(post_feed_time) = DATE(NOW()) AND  and post_message != ''  ORDER BY post_like_count DESC";

$query = mysql_query($sql);
    $result = array();
    while($row=mysql_fetch_assoc($query)){
      $result[$row['page_caterory']][] = $row;
    }

foreach($result[1] as $i => $cat1){
if($i <= 14){
echo xx;
}
}

foreach($result[2] as $i => $cat1){
if($i <= 14){
echo xx;
}
}

select * FROM tbl_page,tbl_post
WHERE tbl_page.page_id = tbl_post.post_page
AND DATE(post_feed_time) = CUR_DATE() AND page_category = 2 AND post_message > ''

SELECT * 
FROM (
	select * from tbl_page where .......
) tb1
inner join (
	select * from tbl_post where .......
) tb2
on tb1.page_id = tb2.post_page
