My DNS server is pretty fast under ideal circumstances (under 0.07ms per reply using 2000 era hardware as per https://maradns.samiam.org/speed.comparison.html https://maradns.samiam.org/speed.comparison.html ). I’m sure you’re not getting 1ms in less-than-ideal circumstances (router overloaded and dropping packets, which sometimes happens on my home network), where that extra DNS server starts to really slow things down.
