mysql - 長い mysql クエリ

Question

質問があります

SELECT * 
  FROM tbl_auction_listing 
  JOIN tbl_user ON tbl_auction_listing.user_id = tbl_user.user_id 
  JOIN tbl_subject ON tbl_auction_listing.subject_id = tbl_subject.subject_id 
  JOIN tbl_medium ON tbl_auction_listing.medium_id = tbl_medium.medium_id 
  JOIN tbl_style ON tbl_auction_listing.style_id = tbl_style.style_id 
 WHERE tbl_auction_listing.item_number = '2736503389’

これにより、サイトの速度に問題が発生し、サイトがクラッシュすることもあります。これを複数のクエリに分割した方がよいでしょうか?
