Slow Request on every page call

I noticed that on every page call, the function wcusage_page_contain_shortcode() is executed that takes about 0.2 sec to finish.
That slows down the page quite a bit and I do not understand why this database query is necessary on every page call. It looks like this should be call once and then be stored globally, since it’s not a specific call for every page, it’s a very generic query.
