Good plugin, but doubles the loading time

Hi!
Thank you for a great plugin, love it.
Unfortunately there are some problems with it at the moment.
* It doubles the loading time. I have debugged my site thoroughly, disabled all plugins but the loading time and queries shoots up to the double when enabling the plugin. It is heavy on category pages.

Also disabled shipping calculation as suggested in other threads.
The loading time goes from 5s to 11s and the queries from 2800 to 3800 on Woocommerce category pages.

There seems to be another bug with Bogo deals since last version as well, BOGO deals: Buy 1 get 2 deals does not show the discounted prices in archive pages until adding both products, even if “before matching condition” is selected. Previously you would see all prices discounted after adding one. Is this a known bug?

Thanks.
