[SmartCrawl Pro] SEO (slow SQL queries)

Hi people, your plugin (SmartCrawl v2.5.0) has a slow queries, that 48 hours works. This happens if you have 100 products and more than 50 keywords per each produkt.
You have 48 times INNER JOIN in your logic. It ist not a good idea 🙁
There is an example of your query:

SELECT SQL_CALC_FOUND_ROWS  wp_posts.ID FROM wp_posts  INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id )  INNER JOIN wp_postmeta AS mt1 ON ( wp_posts.ID = mt1.post_id )  INNER JOIN wp_postmeta AS mt2 ON ( wp_posts.ID = mt2.post_id )  INNER JOIN wp_postmeta AS mt3 ON ( wp_posts.ID = mt3.post_id )  INNER JOIN wp_postmeta AS mt4 ON ( wp_posts.ID = mt4.post_id )  INNER JOIN wp_postmeta AS mt5 ON ( wp_posts.ID = mt5.post_id )  INNER JOIN wp_postmeta AS mt6 ON ( wp_posts.ID = mt6.post_id )  INNER JOIN wp_postmeta AS mt7 ON ( wp_posts.ID = mt7.post_id )  INNER JOIN wp_postmeta AS mt8 ON ( wp_posts.ID = mt8.post_id )  INNER JOIN wp_postmeta AS mt9 ON ( wp_posts.ID = mt9.post_id )  INNER JOIN wp_postmeta AS mt10 ON ( wp_posts.ID = mt10.post_id )  INNER JOIN wp_postmeta AS mt11 ON ( wp_posts.ID = mt11.post_id )  INNER JOIN wp_postmeta AS mt12 ON ( wp_posts.ID = mt12.post_id )  INNER JOIN wp_postmeta AS mt13 ON ( wp_posts.ID = mt13.post_id )  INNER JOIN wp_postmeta AS mt14 ON ( wp_posts.ID = mt14.post_id )  INNER JOIN wp_postmeta AS mt15 ON ( wp_posts.ID = mt15.post_id )  INNER JOIN wp_postmeta AS mt16 ON ( wp_posts.ID = mt16.post_id )  INNER JOIN wp_postmeta AS mt17 ON ( wp_posts.ID = mt17.post_id )  INNER JOIN wp_postmeta AS mt18 ON ( wp_posts.ID = mt18.post_id )  INNER JOIN wp_postmeta AS mt19 ON ( wp_posts.ID = mt19.post_id )  INNER JOIN wp_postmeta AS mt20 ON ( wp_posts.ID = mt20.post_id )  INNER JOIN wp_postmeta AS mt21 ON ( wp_posts.ID = mt21.post_id )  INNER JOIN wp_postmeta AS mt22 ON ( wp_posts.ID = mt22.post_id )  INNER JOIN wp_postmeta AS mt23 ON ( wp_posts.ID = mt23.post_id )  INNER JOIN wp_postmeta AS mt24 ON ( wp_posts.ID = mt24.post_id )  INNER JOIN wp_postmeta AS mt25 ON ( wp_posts.ID = mt25.post_id )  INNER JOIN wp_postmeta AS mt26 ON ( wp_posts.ID = mt26.post_id )  INNER JOIN wp_postmeta AS mt27 ON ( wp_posts.ID = mt27.post_id )  INNER JOIN wp_postmeta AS mt28 ON ( wp_posts.ID = mt28.post_id )  INNER JOIN wp_postmeta AS mt29 ON ( wp_posts.ID = mt29.post_id )  INNER JOIN wp_postmeta AS mt30 ON ( wp_posts.ID = mt30.post_id )  INNER JOIN wp_postmeta AS mt31 ON ( wp_posts.ID = mt31.post_id )  INNER JOIN wp_postmeta AS mt32 ON ( wp_posts.ID = mt32.post_id )  INNER JOIN wp_postmeta AS mt33 ON ( wp_posts.ID = mt33.post_id )  INNER JOIN wp_postmeta AS mt34 ON ( wp_posts.ID = mt34.post_id )  INNER JOIN wp_postmeta AS mt35 ON ( wp_posts.ID = mt35.post_id )  INNER JOIN wp_postmeta AS mt36 ON ( wp_posts.ID = mt36.post_id )  INNER JOIN wp_postmeta AS mt37 ON ( wp_posts.ID = mt37.post_id )  INNER JOIN wp_postmeta AS mt38 ON ( wp_posts.ID = mt38.post_id )  INNER JOIN wp_postmeta AS mt39 ON ( wp_posts.ID = mt39.post_id )  INNER JOIN wp_postmeta AS mt40 ON ( wp_posts.ID = mt40.post_id )  INNER JOIN wp_postmeta AS mt41 ON ( wp_posts.ID = mt41.post_id )  INNER JOIN wp_postmeta AS mt42 ON ( wp_posts.ID = mt42.post_id )  INNER JOIN wp_postmeta AS mt43 ON ( wp_posts.ID = mt43.post_id )  INNER JOIN wp_postmeta AS mt44 ON ( wp_posts.ID = mt44.post_id )  INNER JOIN wp_postmeta AS mt45 ON ( wp_posts.ID = mt45.post_id )  INNER JOIN wp_postmeta AS mt46 ON ( wp_posts.ID = mt46.post_id )  INNER JOIN wp_postmeta AS mt47 ON ( wp_posts.ID = mt47.post_id ) WHERE 1=1  AND wp_posts.ID NOT IN (1212) AND (
