&gt; &quot;...From what I&#x27;ve heard, Azul has a great GC, but the
&gt; throughput is extremely low. It&#x27;s really only a practical
&gt; solution for high frequency finance and places like that
&gt; where latency is everything, and throughput is nothing...&quot;<p>Well, you heard wrong.<p>Zing is used in plenty of throughput-intesive and throughout-centric applications, and sustainable throughput on Zing tends to be higher (not lower) than with other JVMs. E.g. Cassandra clusters tend to carry higher production loads per machine when powered by Zing (compared to OpenJDK or HotSpot on the same hardware). All while dramatically improving their latency behavior and consistency.<p>Specifically, on similarly sized heaps and workloads, the C4 collector&#x27;s throughout is better than CMS&#x27;s and close to ParallelGC&#x27;s. And since it&#x27;s throughput scales linearly with the amount of empty heap configured and since (unlike OpenJDK&#x2F;Hotspot) Zing places no practical pause-related caps on how much memory can be applied, it tends to beat both on efficiency in actual configurations.<p>The notion that good latency behavior has to come at the expense of throughput is just a silly myth. There are plenty of examples that disprove it. Zing&#x2F;C4 is just one of many.
