TTFB & Page speed issue

RE: TTFB & Page speed issue
Detecting Cloudflare in Mumbai is a bug on my sid. The Mumbai agent is running the newer cross-platform agent and it looks like it is not detecting the CDN-specific headers correctly when it is a HTTP/2 connection. I'll have it fixed shortly.

As far as first byte times go, The actual server response time looks pretty good but if the waterfalls are accurate, the initial DNS lookups are pretty slow. I'd recommend enabling packet captures (tcpdump) which are available in the advanced settings and re-running the tests. Then look at the timings for the DNS lookup in the packet capture and make sure they really are that slow.

Given how much Cloudflare touts their DNS performance I'd ping their support team with the test data and packet captures and have them investigate: https://blog.cloudflare.com/cloudflare-f...stest-dns/
