Too slow for a proxy cache of ATS's caliber/audience.

Anyone know how it might compare to Neflix Zuul

I find that hard to believe. As far as I know, Nginx/Lua/LuaJIT still powers almost all of CloudFlares edge services. [1] https://blog.cloudflare.com/pushing-nginx-to-its-limit-with-... [2] https://blog.cloudflare.com/cloudflares-new-waf-compiling-to...
Almost everyone is an end user of Apache Traffic Server without really knowing it. It is used by Yahoo, Apple, Comcast, Wikipedia, AT&T, Cox and many other companies. Some companies that use it at very large scale don't like to talk about what technologies they use.
Been to many ATS meetups, even worked on atscppapi years ago. Very robust plugin capabilities.
Lots of choices in the this space... - this tool (apache traffic server) - regular apache can proxy/cache/route - nginx - traefik - haproxy - envoy - kong - ...more Then it also somewhat intersects with less directly related things in other spaces, like squid, varnish, istio, and so on. Is there some document somewhere that goes over the choices, overlaps, etc?
Which of those can proxy TCP, as opposed to HTTP? Haproxy can.

Although haproxy and nginx cover (for me) almost all use-cases I had to deal with (with OpenResty [1] as a backup), I see one place where ATS could shine: plugins. From examples [2], C API looks sane and well documented, and this is very important if you want to add some custom stuff inside your proxy server without losing your hair. And no, lua isn't the solution here ;) Those who had to deal with nginx plugins, I f…
openresty is (patched) nginx + luajit
haproxy has optional extension with lua as well
CMIIAW, what parent is saying is he does not like lua for this purpose

one of the nice things about haproxy is that pcre is optional. it seems pcre is a hard requirement to compile trafficserver
trafficserver is also much more code, coming from a variety of sources.

This was originally “Yahoo! Traffic Server”, was developed by Yahoo! in the early 2000’s and was used in part to power Yahoo! CDN. At the time Yahoo! relied on Akamai and its own network.
It was developed by inktomi[1]; inktomi was acquired by yahoo in the one of the great extinction events of the early internet. [1] https://en.wikipedia.org/wiki/Inktomi
I was a senior engineer at the time, yet the Inktomi engineers were already very, very senior.
