Hi I have installed the plugin but website is running very slow with the plugin takes long time to load a page example
homepage – damagedrv.com
example page using shortcode for super rss- https://www.damagedrv.com/rv-shows/
The page loads quickly on my side and I see no issue.
The RSS feed is cached. So every 12 hours, when the cache expires, the first load may take time. Subsequent load will be from cache and it will be very fast.
