Am I reading way too far into David's "CoreOS Networking Engineer" title?

Apple has had a CoreOS group for a very long time. Here's a post from 2008 that mentions it: http://lists.freebsd.org/pipermail/freebsd-jobs/2008-October...

Ah got it thanks for clearing that up.

It's had a Core OS group, not a CoreOS group.

Almost any technology low in Apple's stack is called 'Core ...'. A quick search at developer.apple.com yields Core Animation, Core Video, Core Text, Core Graphics, Core Image, Core Data, JavaScriptCore, WebCore, Core Audio, Core Bluetooth, Core Foundation, and Core Media Framework.

That convention started with Mac OS X, when they had to somehow unite the low-level technologies of classic Mac OS and NextStep.

previously they'd call their stuff OpenSomething... OpenDoc, OpenTransport etc.

It would be hard to be worse. If I turn on too much of IPV6 on OSX DNS takes forever (yes I did check the IPV6 config).

breckinloggins• 11 years ago

Can you file a radar for that with the specific things that are causing the slowdown? Radars are always appreciated.

Slow DNS with some configs that involve IPv6 is a known issue on OSX :(

jmount3• 11 years ago

Sure, pay me my consulting rate to run it down and fill out the forms.

I thought (before reading) it had something to do with the X11 xeyes program.

Apple has done amazing things for IPv6 on the client side; first defaulting to IPv6 for link-local traffic, and then being an early adopter of Happy Eyeballs and putting relatively good IPv6 support in their AirPorts.

Many brownie points!

Interesting, now I am not even sure how much credibility can be given to the networking engineers from Apple: we're in 2015 and I still need to manually tune the TCP stack of my mac to get decent download speeds!

shiven• 11 years ago

What tuning parameters are you using and where are you making those changes?

net.inet.tcp.win_scale_factor=8 net.inet.tcp.autorcvbufmax=16777216 net.inet.tcp.autosndbufmax=16777216
