Fundamentals × What Makes a Website Slow?

In this episode of Syntax, Wes and Scott talk through all the reasons your website might be slow, and how you can troubleshoot a slow website such as issues on the server, large assets, caching, CSS, JavaScript, latency, and more.

If you want to know what’s happening with your code, track errors and monitor performance with Sentry. Sentry’s Application Monitoring platform helps developers see performance issues, fix errors faster, and optimize their code health. Cut your time on error resolution from hours to minutes. It works with any language and integrates with dozens of other services.
