How do you tune a JVM performance?

How to Properly Plan JVM Performance Tuning

1. Understand the JVM garbage collector.
2. Be familiar with the common tools for JVM performance monitoring.
3. Have the ability to read GC logs.
4. Perform tuning only when necessary and practical (JVM performance tuning cannot solve all performance problems)

What is JVM performance?

JVM tuning mainly involves optimizing the garbage collector for better collection performance so that applications running on VMs can have a larger throughput while using less memory and experiencing lower latency. …

What helps to improve performance of Java?

Perform profiling and load testing.

Clean up code and revise algorithms.

Avoid recursion when possible.

Upgrade system hardware.

Increase LAN and WAN bandwidth.

Tidy up your operating system.

What is tuning in Java?

In short, JVM tuning requires some tradeoff between metrics like throughput and response time. Java optimization, meanwhile, improves the system overall, when successfully implemented. Java virtual machine (JVM) tuning requires stable memory, processor speed, network bandwidth and hosted applications.

What are JVM options?

Talking about JVM options, then there are three types of options that you can include to your JVM, standard, non-standard, and advanced options. If you try an advanced option, you always use the option with -XX . Similarly, if you’re applying a non-standard option, you use -X .

What is Java profiler tool?

A Java Profiler is a tool that monitors Java bytecode constructs and operations at the JVM level. These code constructs and operations include object creation, iterative executions (including recursive calls), method executions, thread executions, and garbage collections.

Where can I find JVM args?

The directory server provides a means of configuring the Java Virtual Machine (JVM) and Java options for each command-line utility and for the directory server itself. The Java configuration is provided in a properties file, located at instance-dir /OUD/config/java.
