Does it really? With Java’s G1GC the only knob you
may end up having to tune is the max target pause time - which pretty much chooses between better p50 and worse p99 va worse p50 and better p90 - aka throughput vs latency, that are almost inherently opposite ends of the same spectrum. It is not GC-specific that any improvement will fail to increase one of those.
So the actual tradeoff is more whether you want better throughput or tail-latency. To improve the latter, you have a singular command line option of using ZGC as well.
