Configure DNS Efficiently

If you use a nearby DNS provider it provides you a fast lookups. Then keep the TTLs low for dynamic content and high for static pages to optimize cache performance. pick a DNS provider close by and tweak the cache times so your changing pages refresh quickly while your set-in-stone parts stay put longer – that way everyone can find your site in a snap

Upgrade Hardware if Needed
