Java thread dumps are one of the most powerful diagnostic artifacts for understanding application freezes, deadlocks, CPU spikes, and JVM unresponsiveness, but interpreting them accurately is rarely straightforward. Their size, complexity, and sheer volume can make manual analysis overwhelming, especially…
The recent webinar focused on troubleshooting performance issues in customer-managed, on-premise environments. Experts discussed challenges like limited visibility and communication delays, emphasizing the need for essential artifacts for diagnosis. Participants learned practical strategies, including automation workflows and effective communication techniques, to enhance resolution accuracy and reduce turnaround times.
The garbage collection phase in Java applications is important for keeping performance high. Configuring garbage collector threads, including concurrent and parallel threads, can improve application performance. Be careful with manual thread configuration to avoid performance problems. Analyzing thread dumps can help monitor and enhance performance by identifying problem areas and fine-tuning settings.
Detecting CPU spikes in a Java application is important for keeping it running smoothly. This can happen because of things like lots of calculations, user actions, other tasks running in the background, or code that could be made better. The post talks about fixing CPU spike issues in Dell Boomi servers and doing tests to make CPU spikes happen in Boomi using the buggyApp tool. It also mentions using performance monitoring tools for keeping an eye on performance and figuring out why problems happen.
Virtual Threads in Java, introduced in version 21, significantly enhance multi-threaded applications by reducing thread management overhead. This article explores their advantages over traditional platform threads through experimentation involving one million threads. Virtual Threads operate efficiently within heap memory, preventing OutOfMemoryError, and allow easier application scalability and performance improvements.
Discover the power of thread dumps in Android development. Learn what thread dumps are, how to capture them using commands like ‘dumpsys thread’ and ‘jstack,’ and uncover the insights they offer. Explore the effectiveness of ‘fastThread,’ a user-friendly tool that…
Everyone knows about what sorting is. There are so many computer algorithms that have emerged to support sorting. Some of the well-known algorithms are quick sort, heap sort, merge sort etc.
