That is indeed true. But, I remember the time when we were rolling out nginx back in 2000's and exactly the same thing was said about Apache.

We did require some of them[1]. Esp. painful were Transfer-Encoding quirks, and some dances around old HTTP/1.0 backends and request buffering. Compared to NGINX though, it was relatively easy to push these fixes upstream. Community

There is a good discussion of LIFO queue behaviours on the corresponding reddit thread[1], featuring the Google's SRE book, Van Jacobson quotes, and real world examples. [1] https://www.reddit.com/r/programming&#x2

Our train of thought goes like that: * in non overloaded case LIFO/FIFO make no difference[1]. * in an overloaded case LIFO has better reliability properties, e.g. no standing queue and therefore faster recovery times. There are altern

Ouch, that was embarrassing -- thanks for spotting =) Sorry about that -- ESL and stuff. Editors did a hell of a job fixing our English, but errors still slipped in. We'll be fixing grammar (and probably add link to the presentation PD

The main principle here is to reuse as less infra as possible: different dns provider, different hosting, different cert authority, etc. So, debug.github.com is probably worse, than github-debug.com (github.debug should be fine though, and

Early edge network was indeed prototyped in AWS: a simple setup with ELB in tcp mode, nginx and proxy_protocol. Once we've got all data from that experiment: performance, cost, and flexibility included, we've decided to start buil

> It's not like updating this stuff is without risk. Same goes for kernel, libc, all other libraries, and pretty much anything else. This is not an argument for not upgrading them though. Also, sadly, almost all firmware updates fix

Physical locations matters a lot for uploads, mostly because client TCP stack is way less sophisticated. For downloads high RTT can be mitigated by a congestion control that ignores constant packet-loss rates (which are common for high-rtt

I've tried to: 1) give an bcc/perf example to check the need for tuning and verify its effect. 2) give code/docs/paper reference as an embedded link. 3) give a generic monitoring guideline at the start of a "chapter

By "dict" I meant the data we are compressing: these are basically dictionaries for "English to X" translation. What was saying is that there is a strong correlation between size of the data I was compressing and compres

This is a good talk about decomposability of control plane and creating proper abstractions for it. PS. "The ability to master complexity is not the same as the ability to extract simplicity" is a good takeaway. PPS. This is a par

The first draft of the article actually had that reason, but there is also a strong correlation between the size of the dict (these dicts are almost 1Mb, while other languages are closer to 500kb) and compression ratio improvements. Therefo

The article is a bit shallow. It would be nice to see: 1. What flavours of PGO optimizations were applied? What was the isolated impact of each one of them on both speed and size of the code? 2. What tests did they use to "guide"

With the same reasoning you can use nginx as a C runtime.
