    i used wp_query class to get posts from a lot of different categories. after that, i checked and my web need 187 queries to database. it echo result in the footer tag. you can see at the Menu section in footer. it's terrible. i found out wp_query class need 5 query to database when it runs. is it right?
    what function i recommend to use when i want to get posts from a lot of different categories?

    $query = new WP_Query(array('posts_per_page' => 10, 'category_name' => 'tin-tuc'));
    $query = new WP_Query(array('posts_per_page' => 10, 'category_name' => 'tai-lieu'));

    and a lot of alike snippets. i get all of them out and then put into one by one. i found out every snippet need 5 query to database.

    i design my theme by myself. not use any outside plugin.
    help me. thanks
