Did you have tight and consistent latency requirements?

GC pauses are a killer. They can be worked around, but it takes intensive tuning.

The RTB bidder I wrote many moons ago at a startup was fast as hell, but had problems in the 95th percentile of requests meeting the latency targets, due to GC.

The ad servers at the big ad tech heavy weights are in C++.

Of course, people aren't going to be happy when they packets get dropped or the network monitoring software wasn't able to provide a (soft) real time view of what was happening.

Also note I wasn't doing this alone, it was a very big project a mobile operator.

Your experience isn't representative, so there were probably other confounding factors, like the C++ wasn't very well written, or you weren't dealing with petabytes of data or something like that.
