I have specified the post per page to be 3 as arg but it does not seems to work, all the post are being shown up. Not sure why i works if i enable no paging false but pagination shows up.

Array
    (
        [post_type] => post
        [post_status] => publish
        [paged] => 1
        [nopaging] => true
        [posts_per_page] => 3
        [order] => ASC
        [orderby] => none
    )
