We would be glad to help you and find this performance bug in our theme. But we will need your FTP access to do this. Could you please provide us this information?
1. We have disabled wishlist AJAX request so you can check now.
2. Anyway 5.6 time loading for blog pages tells that you have some problems with your server performance. Try to switch to default theme and check. Time loading should be 500-800 ms in this case.
Next time please provide us your admin access please also.
