Avoid multiple page redirects. Potential savings of 1,410 ms
Redirects introduce additional delays before the page can be loaded. Learn more.
Serve images in next-gen formats. Potential savings of 240 KiB

Links to cross-origin destinations are unsafe
Add `rel="noopener"` or `rel="noreferrer"` to any external links to improve performance and prevent security vulnerabilities. Learn more.
