Java's new Z Garbage Collector (ZGC) is very exciting
Java 11 features a new Garbage Collector, the Z Garbage Collector (ZGC), which is designed for very low pause times on huge multi-terabyte heaps. In this article we'll cover the motivation for a new GC, a technical overview and some of the really exciting possibilities ZGC opens up.
Hasnain says:
“So how does it perform? Stefan Karlsson and Per Liden gave some preliminary numbers at their Jfokus talk earlier this year. ZGC’s SPECjbb 2015 throughput numbers are roughly comparable with the Parallel GC (which optimises for throughput) but with an average pause time of 1ms and a max of 4ms. This is in contrast to G1 and Parallel who had average pause times in excess of 200ms.”
