This post explains how to diagnose CPU spike problems that surfaces in the Spring Boot applications.
Spring Boot is a framework for creating Java web applications, but it can experience thread leaks, leading to performance issues. A thread leak occurs when threads retain references after execution, causing resource exhaustion. Proper thread management, including termination, use of thread pools, and handling exceptions, is crucial for preventing leaks and ensuring system stability.
This post examines configuring Virtual Threads in a Spring Boot application that calculates the Fibonacci sum for values starting from 10,000. Using JMeter, a load test with 1000 users reveals similar throughput and average response times for both virtual and native threads, highlighting virtual threads' advantage in lower thread usage without performance gain for CPU-intensive operations.
In this article, we are going to compare the performance of Garbage Collection(GC) of OpenJDK and GraalVM. The GraalVM is a popular open source JVM implementation in Java with a capability to run applications as native images. Apart from that, it…
In the world of software engineering, where innovation meets precision, yCrash emerges as a toolkit designed to enhance Java performance monitoring and diagnostics. A DevOps engineer, would delve into this article as a guide that shares the practical advantages of…
ConcurrentHashMap enhances multi-threaded applications by incorporating parallelism, introduced in Java 1.8. It allows tasks to be divided into subproblems solved concurrently, optimizing processes through the ForkJoinPool API. Parallelism can be controlled via a threshold, improving performance significantly with larger datasets while enabling efficient thread management.
