i wanted to know somethings about the firebug,
when i try to load a page with firebug opend, it start the time lines.

what is :

waiting,
reciving,
DomContentLoaded,
Load,

mysql queries what affect from the list ? i see that more mysql queries i am adding, the reciving part is increasing.

let me paste a request that ihave used on my core , to generate a dynamic link or content.

```
function getContent($id = '') {
    $id = mysql_real_escape_string ($id);
    $sql = 'SELECT id,post_title,post_content FROM wp_posts WHERE post_category="67" ORDER BY post_date DESC LIMIT 1';
    $res = mysql_query($sql) or die (mysql_error());    

if (mysql_num_rows($res) !=0):
    while ($row = mysql_fetch_assoc($res)) {

    // this remove caption from wordpress, get 450 words to be used for exerpt, encode html,
    $mycontent = $row['post_content'];
    $mycontent = strip_tags($mycontent);
    $mycontent = substr($mycontent,0,250);
    $mycontent = preg_replace("/\[caption.*\[\/caption\]/", '', $mycontent); 
    $mycontent = htmlentities($mycontent);

    //encode the words for html
    $title = $row['post_title'];
    $title = htmlentities($title);

    echo '

    <<h1><a href="single.php?id='.$row['id'].'">'.$title.'</a> </h1>
    <div class="cssclass"> '.$mycontent.' </div>

    '; //echo
}
    else:
        echo 'This page dosnt exist.';
    endif;
} // end 

```

Is any thing wrong on this code or its normal, my db is about 75.000 lines.

Thank you for reading this post.
