Optimize a SELECT code (vB code)

I'm having issues on my server with a huge amount of slow queries like this one:

PHP Code:


		
			
SELECT postid, visible, userid



                        FROM post AS post



                        WHERE threadid = 124608                              



                                AND visible IN (1



                                ,2



                                )



                        ORDER BY dateline;

Only thing that changed is the threadid.

I have query times of 20-50 seconds on each of these queries. It's bogging down the server.

So how can that code be optimized further? What about separating the dateline ordering into a php based sorting (array sort).

I think it may be an issue with your mysql server and not really require optimization.
