Я пытаюсь получить элемент и дополнительные сведения, которые находятся в отдельных таблицах

Есть 4 таблицы ebay_items, amazon_items, item_attributes, import_items_logs Это то, что я хочу в результате,

  1. ebay_items и amazon_items должны совпадать (ebay_items. id = amazon_items.related_ebay_item_id)

  2. также item_attributes (amazon_items.id = item_attributes.amazon_id) и import_items_logs (ebay_items.id = import_items_logs.ebay_id) 10 записей необходимы, если есть какие-либо записи 1023 *

Это мой запрос, когда я бегал по локальной сети, это занимает 50 + se c или amazon server, это занимает 12se c до fini sh. Что не так я делаю здесь. Всего записей 2600. Я не знаю, почему это слишком медленно
