Large JavaScript bundles delay interactivity. Split code by route or defer non-critical scripts.
JavaScript bundle is large — code-split routes and lazy-load off-screen components to defer.

Each request adds latency. Bundle small files, use sprites, or eliminate unnecessary requests.
High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.

Current Resource Hints
15 resource hints configured
Fonts are always fetched as crossorigin=anonymous; a preload without the attribute creates a different cache key, so the browser refetches when the actual font request happens. Sample: //lorienthaus.com/cdn/fonts/montserrat/montserrat_n4.81949fa0ac9fd2021e16436151e8eaa539321637.woff2, //lorienthaus.com/cdn/fonts/montserrat/montserrat_n5.07ef3781d9c78c8b93c98419da7ad4fbeebb6635.woff2, //lorienthaus.com/cdn/fonts/montserrat/montserrat_n7.3c434e22befd5c18a6b4afadb1e3d77c128c7939.woff2 (+1 more). Add `crossorigin` (or `crossorigin="anonymous"`) to each preload.
Performance issues directly impact user engagement and conversion rates.
preconnect already does the DNS lookup; adding dns-prefetch to the same origin is at best a no-op. Sample: https://cdn.shopify.com, https://www.googletagmanager.com. Remove the redundant dns-prefetch entries.
Performance issues directly impact user engagement and conversion rates.
The same href shouldn't appear in multiple hint rels -- one wins, the others are wasted markup and may confuse cache behavior. Sample: https://cdn.shopify.com (preconnect+dns-prefetch), https://www.googletagmanager.com (preconnect+dns-prefetch), //lorienthaus.com/cdn/fonts/montserrat/montserrat_n7.3c434e22befd5c18a6b4afadb1e3d77c128c7939.woff2 (preload+preload).

42% of JavaScript execution time comes from third-party scripts.
Third-party scripts (analytics, ads, social, A/B testing) often dominate execution time — every one is a perf-and-privacy tax.
Learn more ▾ ▴
Each third-party script is a black box: you don't control when it loads, what it executes, or how much it grows. They often account for a major share of total blocking time on average sites (HTTP Archive's Web Almanac documents the trend). Audit which ones you actually need, defer the rest, and use facade patterns (lite-youtube, lite-vimeo) for embedded media.
