Current Resource Hints
6 resource hints configured
preconnect already does the DNS lookup; adding dns-prefetch to the same origin is at best a no-op. Sample: https://cdn.fontcdn.ir, https://cdn.jsdelivr.net, https://cdn.fontcdn.ir (+1 more). 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.fontcdn.ir (preconnect+dns-prefetch), https://cdn.jsdelivr.net (preconnect+dns-prefetch).
