Почему NVMe не всегда ускоряет сайт: смотрим на latency, p95/p99 и профиль нагрузки

У дисковой подсистемы слишком хорошая репутация в тарифных таблицах и не самая однозначная в инженерных обсуждениях. В первом случае нам продают гигабайты в секунду, во втором часто говорят, что для веба диск почти не важен. Я работаю контент-маркетологом в Scalehost и по работе регулярно разбираю темы, связанные с производительностью веб-проектов. Вопрос “нужен ли сайту NVMe или это просто маркетинговая галочка” возникает так часто, что мне захотелось собрать его в один технически внятный разбор.

Common misconceptions about how to optimize LCP  |  Blog  |  web.dev

Explore common misconceptions about optimizing Largest Contentful Paint (LCP) by looking beyond image optimization and considering factors like Time to First Byte (TTFB) and resource load delay.

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.

Meet 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.
