I've been using SEO Booster for about three weeks now, and while it's a helpful tool, it adds about 400-500kb of bloat to your pages, which significantly slows them down. Because of this, I can't use all the features the plugin offers. Thankfully, I use Perfmatters on my site to selectively choose which scripts run and which don't. I was honestly surprised by how much weight it adds to pages—I don't recall seeing anything this resource-intensive in my 15 years in this field.
