Hey, as far as Feedzy is concerned, it automatically adds caching to feeds, so it shouldn’t affect the website’s speed.

But if you’d like to investigate further, here’s a more detailed review of the top RSS plugins https://wpshout.com/blog/best-rss-to-post-wordpress-plugins/

Hey George, we try to help your site’s performance as much as possible with WP RSS Aggregator, but yes, it does affect performance if the hosting is not adequate for the job. It is a server-intensive process to import content continuously, but it’s nothing that a good host can’t handle 🙂

Hey Steven, any particular reason you’d say that?

WP RSS Aggregator’s add-ons can achieve what you’re looking for. As you may understand, developing add-ons as extensive as our Feed to Post add-on is no small feat. It requires a dedicated development and support team and years of work and gathering feedback. Giving that away for free results in the team being unable to support itself, so the plugin would die out. We don’t want that.

I’d just like to point out that, in the past, some individuals did provide extensive free versions of plugins like ours. These individuals could not keep up with the users, and the plugins very quickly died out and were removed from the plugin repository. This is further proof of what I described above.
