Measuring Unikernel Cold Boot Time with Perf
A while back ago CDNs would market on their TTFB - that is the 'time to first byte'. It sounds like a really important number and the lower you can make it the more impressive it looks. At the end of the day though it doesn't really matter cause a single image can be tens of kilobytes or even megabytes in size. A single page can have 80 some odd requests and transfer multiple megabytes in resources. So while it is interesting it's a bit of a vanity metric.
Tim VereeckeMeet UNO, the missing link in any TTFB analysis.
Without Unattributed Navigation Overhead you are lost, because TTFB is rarely the sum of Redirect+DNS+TCP+TLS in the field!
Understanding UNO has saved me countless hours in RUM.

TTFB happens before user-centric metrics such as First Contentful Paint (FCP) and Largest Contentful Paint (LCP), we recommend that your server respond to navigation requests quickly enough so that the 75th percentile of users experience an FCP within the "good" threshold. As a rough guide, most sites should strive to have a TTFB of 0.8 seconds or less.
Nicolas HoizeyJudging by this @speedcurve graph comparing TTFB from last 3 months to the 3 months before, it looks like TTFB has improved lately with #Netlify, while it has degraded with #Cloudflare:
I'm currently using Cloudflare in front of Netlify, but I'm not sure it's worth it anymore. 🤔
