Go 1.1 performance improvements, part 3

Have you tried libdispatch (http://en.wikipedia.org/wiki/Grand_Central_Dispatch)? It’s pretty darn powerful.

I'd like to see a side by side comparison of this to Go.

If you are on Objective-C,

If using C++

std::async, std::future and respective std queues.

Intel TBB

If using C#

TPL and async/await

"It important to note that queues are not a panacea for replacing threads."

Powerful, but not quite as good as Go. Seems to me you still end up writing callbacks.

Don't get it. Please note I do have Go experience.

You can write entire concurrent systems in Go without writing callbacks.

You can do the same in other language frameworks as well.

On iOS? Is there a one-stop tutorial that covers this?

XPC services implemented in golang would be very handy - here's hoping iOS 7 gains full XPC support.
