Top Linux Web Servers: Pros and Cons
Now that we know their advantages and disadvantages, which web server is the best? The answer depends on your use case. Nginx is a very fast and powerful option, Apache is a great general-purpose web server, while LiteSpeed represents a premium alternative. Caddy works great if you need simplicity, while Lighthttpd works best when resources are low.
