Which Shopify apps slow down my site the most?

As a Shopify store owner, I'm increasingly concerned about my website's performance and how various apps might be impacting my site speed. I've noticed some sluggishness in page load times and suspect that some of the apps I've installed could be the culprit. I want to understand which types of apps are most likely to cause performance issues, how to identify slow apps, and what strategies I can use to maintain a fast, responsive online store without sacrificing functionality.
