The document summarizes a performance study comparing Azul Systems' Zing Java runtime to Oracle's HotSpot JVM. The study found that Zing eliminated all garbage collection pauses over 2.5 milliseconds at the 99.999th percentile, while HotSpot had pauses up to 115 milliseconds at the 99th percentile. For latency-critical applications, Zing reduced outliers and delivered more fine-grained control over data distribution than HotSpot. The document concludes that for Java-based data distribution, a well-tuned Zing runtime outperforms a well-tuned HotSpot.
