In this post, let's learn more about this intern() function. 1. How does the String intern() function work? In Java heap memory, a pool of string objects... Continue Reading →
c1, c2 compiler threads are created by Java virtual machine to optimize your application's performance. Occasionally these threads will tend to consume high CPU. In this post, let’s learn little more about c1, c2 compiler threads and how to address their high CPU consumption. After reading this post, terminologies like Hotspot JIT, c1 compiler threads,...

The industry has seen cutting-edge Application Performance Monitoring tools and infrastructure monitoring tools. These monitoring tools are great at answering the question: 'What is the problem?'' but not, Why does the problem happen? yCrash attempts to answer this question. It captures 360-degree artifacts from your technology stack such as Garbage collection logs, thread dumps, heap dumps,... Continue Reading →
When we launch applications, we specify the initial memory size and maximum memory size. For the applications that run on JVM (Java Virtual Machine), initial and maximum memory size is specified through ‘-Xms’ and ‘-Xmx’ arguments. If Java applications are running on containers, it's specified through ‘-XX: InitialRAMPercentage’ and ‘-XX: MaxRAMPercentage’ arguments. Most enterprises set... Continue Reading →
Java developers tend to use 'java.util.UUID#randomUUID()' API, to generate a UUID (Universally Unique Identifier) number (i.e., 'b8bbcbed-ca07-490c-8711-5118ee0af2f9'). Under certain circumstances, using this API can affect your application’s availability. Let’s discuss this API in this post with a real-world example. How does 'java.util.UUID#randomUUID()' API works? java.util.UUID#randomUUID() API internally uses 'entropy' in the operating system to generate... Continue Reading →
