This is an investigative piece on the performance of string deduplication in different versions of Java. The investigation compared Java versions 11, 17, and 21 and their ability to remove duplicate strings. It utilized a WebCrawler application and JMeter load testing to gather data. The findings revealed that Java 11 outperformed versions 17 and 21, eliminating 34.3% of duplicates in 1,264.442 milliseconds. However, newer versions showed a decline in performance, deduplicating fewer strings over longer periods of time.
In this post, we would like to share our real-world experience in optimizing a Java application which was controlling the robots in a warehouse. This application would give instructions to the robots in the warehouse on what actions to perform.... Continue Reading →

Java Concurrent Mark & Sweep (CMS) algorithm is known for concurrently marking and sweeping the memory regions without a significant pause. However, the Concurrent Mark & Sweep algorithm took an unexpected turn when it was deprecated in Java 9 and... Continue Reading →
Java Concurrent Mark & Sweep (CMS) algorithm operates by dividing the garbage collection process into multiple phases, concurrently marking and sweeping the memory regions without a significant pause. While its design brings benefits in terms of reduced pause times, it... Continue Reading →
Tailored for simplicity and effectiveness, the Serial GC operates with a single-threaded approach, making it particularly relevant for smaller-scale applications and scenarios where stringent latency requirements aren't the primary concern. In this post, we will explore techniques to tune Serial... Continue Reading →
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... Continue Reading →
In Java, the finalize method has been part of the language since its early days, offering a mechanism to perform cleanup activities before an object is garbage collected. However, using finalizers has come under scrutiny due to several performance-related concerns.... Continue Reading →
Uber focused on reducing the cost of compute capacity by improving efficiency. They saved 70K cores across 30 Mission-Critical Services by doing Go GC Tuning. Here, we are going to summarize how they implemented it, what they have achieved, and... Continue Reading →
