Reducing P99 Latencies with Generational ZGC

With the low-latency garbage collector ZGC, GC pause times are no longer a big problem in Java. With sub-millisecond pause times there are instead other things in the GC and JVM that can cause application threads to experience unexpected latencies. This talk will dig into a specific use where the GC pauses are no longer the cause of unexpected latencies and look at how adding generations to ZGC help lower the p99 application latencies.
