Short answer: No.
1. DNS Lookup
It depends on few things
A) TLD server speed
You’re using .com which has decent speed. Some TLD like .io, .xyz are slowest. Read case-study.
B) Authoritative Nameservers:
You’re using Cloudflare NS. It’s fast enough.
C) Cache status
Increase TTL can help. Overriding isn’t possible with CF Proxy but only in case of DNS only mode.
Increasing traffic at site can help indirectly in improving DNS lookup time because mosf of the time response would be cached in the ISP DNS resolver. In other words, a popular site can have faster DNS lookup time compared to a fairly new domain with less or no real-time traffic.
2. Server Response Time (also known as TTFB)
A distance between server to testing location will impact the TTFB. Longer distance, high TTFB. Shorter distance, fast TTFB. To mitigate this issue, you have two ways -
If you get majority of traffic from a single country in this case avoiding Cloudflare or any proxy would be better in most cases. Apart from that using country-based server can help in achieving faster performance.
For globally faster TTFB under 100ms, traditional page caching plugin isn’t sufficient. You need to cache pages at edge server of CDN via Sucuri or Cloudflare.
