Can confirm.

I work at two ad-tech related companies, one large one medium, both use Java from the beginning. And I know other company using Python/Golang as well.

Didn't know C(not C++) is particular popular until today. Note that ad company are pretty business focused, add or remove features for big clients are pretty common, so development efficiency matters a lot.

We went from C++ to Go, and started to auto-lose any auctions whose bid requests were in progress during a GC cycle. Go 1.1/1.2 had atrociously long GC pauses (sometimes up to 500ms). You are correct that development efficiency was very important, so losing the auctions was justifiable.

Are things different with Go 1.5/1.6 now that GC has start to be optimized?

As of Go 1.5 (1.6, released last week, makes further improvements):

> The "stop the world" phase of the collector will almost always be under 10 milliseconds and usually much less.

Not sure, sorry. I haven't written any high-performance stuff in it since 2014.
