wpdiscuz: too many SQL queries

I love your plugin, but I can't use it because of big amount of SQL queries. My pages usually generated with 30 queries, but after I enabled plugin the number of queries increased to 100+.

The plugin calls 60 or more SQL queries on pages with comments. Many of them has something to do with notifications. I disabled all of the notification in wpDiscuz options, but all of these notification queries still appear. There are too many queries like this:

• WC_DB_Helper->wc_is_user_subscription_confirmed
• WC_DB_Helper->wc_has_post_notificatio
• WC_DB_Helper->wc_has_comment_notification
• WC_DB_Helper->wc_has_all_comments_notification

Is there any way to reduce the number of queries?

Sorry for my english.
