Uber Engineering Tricks of the Trade: Tuning JVM Memory for Large-Scale Services

The problem is that Java 7 is 10 years old, it means that you are missing 10 years of optimization. For GCs that's a lot.

GCs before ~2010 have been optimized for throughput more than for latency. Since then, you can choose.

Since 10 years, G1 let you set your maximum pause time and you get a huge warning if it miss that target, ZGC or Shenandoah are from the beginning latency first, throughput second.

I last tuned Java 6 in about ~2009 and I was a bit shocked at how familiar most of this article sounded...

Like your handle, too.

Any advise on good / recent sources of information about the various GC algorithm in the recent JVM ?
