Spring Boot is Slow… Until You See This 😳 | Virtual Threads in Spring Boot

Spring Boot Performance Deep Dive | Virtual Threads vs Thread-Per-Request If you're building Spring Boot microservices, you've probably used the default Tomcat thread-per-request model… but have you ever tested how it behaves under real load? In this video, we go beyond theory and prove everything with real benchmarking. What you’ll learn How Spring Boot + Tomcat actually handles requests internally Why the thread-per-request model breaks under load What really happens during blocking I/O operations Platform Threads vs OS Threads vs CPU cores (simplified) How Virtual Threads (Java) work under the hood Mounting / Unmounting explained visually Why Virtual Threads improve throughput (not latency) When Virtual Threads can actually slow your application Full Apache Benchmark (ab) testing with real results Virtual Threads vs Thread-per-request → Side-by-side comparison Real Experiment Included We simulate real-world load using Apache Benchmark (ab) and compare: Default Spring Boot behavior Limited thread pool (under pressure) Virtual Threads enabled You’ll clearly see: Response time differences Throughput improvements Failure scenarios under load Important Takeaway Virtual Threads are powerful… but NOT a silver bullet. They: Improve scalability for I/O-bound applications Do NOT improve CPU-bound workloads Do NOT reduce latency of slow APIs Who should watch this?
