Sub-10 ms Latency in Java: Concurrent GC with Green Threads

I want memory allocation to run in constant time, so I can achieve low latency. That's the point of concurrent GCs - they run in the background to free up memory.

I know they run in the background... but I don't think they run in the background if there's nothing to do, do they?

A JVM with default settings will happily allocate more memory without attempting to even run a single GC cycle until it hits the configured heap size. Once it hits the limit it will try to run the GC.
