Is Java Virtual Threads lightweight?

Java virtual threads consume significantly less memory compared to platform threads, demonstrated by programs creating 10,000 threads. While virtual thread creation is faster, both types use similar CPU resources and execution times when performing tasks. Adopting virtual threads can enhance memory efficiency and response time in applications with numerous threads or high stack sizes.

Java Virtual Threads – Easy introduction

Java virtual threads, introduced in JDK 19, enhance application availability, throughput, and memory efficiency. Unlike platform threads that remain allocated, virtual threads utilize operating system threads only during active processing. This feature leads to reduced memory consumption and improved performance, making it an efficient choice for threading in Java applications.
