However, there is excitement around Starlink for other reasons – namely, the implications it might have for internet speed and latency – even by just a small amount (20 milliseconds on average). Starlink’s Goal: Reduce Internet Latency. What does Starlink and Reduced Latency have to do with me?

I previously wrote about Netflix in [2015] and [2016], and if you are interested in what it's like to work here, I already covered much in those posts. As before, no one at Netflix has asked me to write this, and this is my personal blog and not a company post. A latency outlier issue that happened every 15 minutes. Time flies!

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. The change was obvious in the production graphs, showing a drop in write latencies: Once tested more broadly, it showed the write latencies dropped by 43%, delivering slightly better performance than on CentOS.

We'll likely open source the new one at some point and have a post about it on the Netflix tech blog. ## Case study: Facebook Facebook are advanced users of BPF, but deep details of how they run the tools fleet-wide aren't fully public.

JavaScript-Heavy # Since at least 2015, building JavaScript-first websites has been a predictably terrible idea, yet most of the sites I trace on a daily basis remain mired in script. [1] The blog you're reading loads over a single connection in ~1.2 and 75KiB of JavaScript. These are generous targets.

There are different considerations when deciding where to allocate resources with latency and cost being the two obvious ones, but compliance sometimes plays an important role as well. The move to the cloud is projected by 2015 see a reduction of 30% in IT infrastructure costs, which amounts to $7.2 blog comments powered by Disqus.

Requirements In a previous blog post, we discussed Delta , a data enrichment and synchronization platform. In our Delta blog post , we also described use cases beyond data synchronization, such as event processing. Supports any kind of output , so that the output can be a stream, datastore, or even an API. Schema store integration.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.

You may have read some blog posts or heard conference talks on this topic and think you know the answers. One question I’ve often encountered is, “Why do we need HTTP/3 so soon after HTTP/2, which was only standardized in 2015?” Robin Marx. 2021-08-09T11:00:00+00:00. 2021-08-09T15:05:19+00:00. Why Do We Need HTTP/3?
