Key Takeaways Virtual threads are an important advancement in Java concurrent programming, but they do not offer a clear advantage over Open Liberty’s existing autonomic thread pool for running typical cloud-native Java workloads. For CPU-intensive workloads, throughput is lower with virtual threads than with Open Liberty’s thread pool for currently unclear reasons. Virtual thread ramp-up time from idle to maximum throughput is quicker than Open Liberty’s thread pool due to its thread-per-reques...
