My point is that most truly latency sensitive applications, in GC'd languages or not, don't do any allocation/deallocation on the hot path. Memory management is just too slow.
So GC twiddling is a red herring in those environments, though using manual memory techniques on the JVM may obviate the major reasons to use it in your particular cases. Lots of teams make the engineering decision the other way and use the JVM in usages that require more consistent latencies than RTB requires.
