As it is possible to reduce the load on the database server for a database?

Question

I'm looking at the main page that the request comes from a great plugin Advanced Feature Questions. As it can reduce the load to optimize the query to the database.

SELECT  qa_posts.postid, qa_posts.title, qa_posts.content, qa_posts.format, qa_posts.userid,
                qa_users.userid, qa_users.email, qa_users.handle, qa_users.avatarblobid, qa_users.avatarwidth, qa_users.avatarheight, qa_users.flags
                FROM qa_posts
                LEFT OUTER JOIN qa_users ON (
                    qa_posts.userid = qa_users.userid
                )
                WHERE qa_posts.featured=1
                ORDER BY qa_posts.created DESC
                LIMIT 5;
    264.46 ms - 5 rows - 12 columns

Answer 1

So is this the code you have modified for the plugin and it has reduced the server load? If that is the case I would say thanks to provide me a code and will implement in the very next release.
