Hi,
I was inspecting my mysql slow log today and saw hundreds of slow queries like these:
# User@Host: mywebsite[mywebsite] @ localhost [] Id: 12735736
# Query_time: 3.670198 Lock_time: 0.000252 Rows_sent: 11430 Rows_examined: 34290
SET timestamp=1411894703;
SELECT * FROM wp_postmeta a, wp_posts b WHERE a.post_id=b.ID AND b.post_status!='trash' AND (a.meta_key = '_pprredirect_active' OR a.meta_key = '_pprredirect_rewritelink' OR a.meta_key = '_pprredirect_newwindow' OR a.meta_key = '_pprredirect_relnofollow' OR a.meta_key = '_pprredirect_type' OR a.meta_key = '_pprredirect_url') ORDER BY a.post_id ASC;
# User@Host: mywebsite[mywebsite] @ localhost [] Id: 12735728

SELECT * FROM wp_postmeta a, wp_posts b WHERE a.post_id=b.ID AND b.post_status!='trash' AND (a.meta_key = '_pprredirect_active' OR a.meta_key = '_pprredirect_rewritelink' OR a.meta_key = '_pprredirect_newwindow' OR a.meta_key = '_pprredirect_relnofollow' OR a.meta_key = '_pprredirect_type' OR a.meta_key = '_pprredirect_url') ORDER BY a.post_id ASC;

SELECT * FROM wp_postmeta a, wp_posts b WHERE a.post_id=b.ID AND b.post_status!='trash' AND (a.meta_key = '_pprredirect_active' OR a.meta_key = '_pprredirect_rewritelink' OR a.meta_key = '_pprredirect_newwindow' OR a.meta_key = '_pprredirect_relnofollow' OR a.meta_key = '_pprredirect_type' OR a.meta_key = '_pprredirect_url') ORDER BY a.post_id ASC;
The questions i have are these:
1- Why is this plugin selecting all the redirected posts instead of selecting the one it needs? I have 10,000 redirected pages, so it makes my website super slow!
2- Is this plugin selecting all the redirects and then processing them in php code?
3- Will there be a fix for this problem?
