Sounds believable, but at the time we were stuck at 1.6 and had a significant drop in traffic due to JSSE and non-existing support of "modern" TLS Cipher Suites and TLS extensions (we even had problems with SNI, years after introduction)...

We were using C because epoll made it possible for us to compete, but the Java reactivex stuff were lagging behind.

Moving to a completely different language and platform was easier than moving from Java 6 to Java 8? Why were you stuck on 6 otherwise?

Go may very well have been through best fit for you. However, saying that Java's problem was that you couldn't upgrade from 1.6 yo 1.8 but you could introduce a completely different language doesn't make much sense to me.

Why couldn't you have just put a reverse proxy in front of your java?
