Java Development without GC

All products developed by Coral Blocks have the very important feature of leaving ZERO garbage behind. Because the latency imposed by the Java Garbage Collector (i.e. GC) is unacceptable for high-performance systems and because it is impossible to turn off the GC, the best option for real-time systems in Java is to not produce any garbage at all so that the GC never kicks in. Imagine a high-performance matching engine operating in the microsecond level, sending and receiving hundreds of thousands messages per second. If at any given time the GC decides to kick in with its 1+ millisecond latencies, the disruption in the system will be huge. Therefore, if you want to develop real-time systems in Java with minimal variance and latency, the best option is to do it right without creating any garbage for the GC. In this article we will discuss best practices and how you can use Coral Blocks’ MemorySampler utility class to help you accomplish this critical goal. Continue reading
