Difference Between 32-bit and 64-bit JVM in Java

One does not need to know the difference unless developing a performance-critical application. The minor distinction between 32-bit and 64-bit JVMs would make little difference in your application.

Now coming onto the differences where we will be listing out some key differences between 32-bit and 64-bit Java Virtual Machines are listed below in which we are comparing them alongside based on the concessive factors which are as follows:

1. In a 64-bit JVM, you can specify more memory for heap size than in a 32-bit JVM; for example, in a 32-bit JVM, the theoretical maximum memory limit is 4GB, whereas 64-bit is much higher.
2. The 64-bit JVM is especially useful for Java applications with large heaps, such as those that use more than 100 GB of memory as a maximum.
3. Because the size of the OOP (Ordinary Object Pointer) has increased from 32 to 64 bits, the same Java application will use more memory in the 64-bit JVM than in the 32-bit JVM. You can get away with it if you use the JVM option -XXCompressedOOP, which tells JVM to use 32-bit pointers.
4. The next major change which is seen is that in the 64-bit JVM architecture is the object header size, which is now 12 bytes instead of 8 bytes in the 32-bit JVM. Another change is the size of internal references, which can now be up to 8 bytes, whereas the 32-bit JVM can only be up to 4 bytes.
5. There is a separate installer for the 32-bit and 64-bit JVM’s.
6. Client JVM is only available for 32-bit JVM and not for 64-bit.

As above, we have seen such differences but do remember a note on how can 64-bit JVM performance be slower than 32-bit JVM?

This is because each native pointer in the system takes up eight bytes instead of four. The loading of this additional data increases memory usage, which results in slightly slower execution depending on how many pointers are loaded during your Java program’s execution. The Java virtual machine gains some extra registers that it can use to create more efficient native instruction sequences. When comparing 32-bit to 64-bit execution speed, these extra registers increase performance to the point where there is often no performance loss at all.

Certain points are there to be taken into consideration while migrating from a 32-bit JVM to a 64-bit JVM are as follows:

Factor 1: GC Pause times

The primary motivation for switching from 32-bit to 64-bit JVM is to increase heap size (i.e. -Xmx). When you increase heap size, your GC pause times will automatically increase because there is no more garbage in memory to clear. Before performing the migration, you must perform proper GC tuning; otherwise, your application may experience a pause of several seconds to a few minutes. To come up with the right GC settings for the newly increased heap size, you can use tools like GCeasy.

Factor 2: Native Library

If your application accesses native libraries through the Java Native Interface (JNI), you’ll need to upgrade the native libraries as well because only 32-bit native libraries can be used by 32-bit JVM. Similarly, a 64-bit JVM can only use native libraries that are 64-bit.

• If your application’s heap size (i.e. -Xmx) is less than 2GB, it’s a no-brainer. Use a 32-bit JVM. (< 2GB Memory)
• If your application requires more than 2GB of memory, it’s a no-brainer. Definitely go with 64-bit JVM (> 2GB memory)

Let us now see the differences in a tabular form that are as follows:

32-bit JVM	64-bit JVM
In 32-bit JVM we can have less memory for heap size than in 64-bit JVM.	In 64-bit JVM we can specify more memory for heap size than in 32-bit JVM.
The limit for maximum memory in 32-bit is useful for 4G connectivity.	It is particularly useful for java applications with large heaps.
It has its own installer.	It has an installer different from the 32-bit JVM.
The header size of 8 bytes.	The header size of 12 bytes.
The size of internal references is 4 bytes.	The size of internal references is 8 bytes.

Review Java Virtual Machine

Java Virtual Machine is the name that Java Runtime Environment was known for a time.

Plenty of websites use Java technology to enrich visitors’ experience, from bank websites to video game webpages, all require Java to function correctly.

Formerly known as Java Virtual Machine (JVM), the program was required to run web pages using Java. The JVM is now known as JRE (Java Runtime Environment) and can be installed on Windows, Mac, and Linux.

With JRE (Java Runtime Environment) and viewing web pages that use Java, you can run all those applications that have been developed in the Java programming language and that have the extension .jar.

Once you have installed the JRE, the program will take care of updating automatically, and this way, we will always have the latest version. There is a chance that your computer already comes with the pre-installed JRE, so if it is a very old version, we may have to uninstall it by hand to install the latest version subsequently.

JRE is virtually indispensable in all computers because sooner or later, we will use a program or website that you use Java, requiring us to have Java Runtime Environment installed.

Java Virtual Machine (JVM) Download & Install for Windows 10/8/7

What is a Java Virtual Machine? A lot of users are confused about it and don’t know where to get the Java Virtual Machine download pack. In this post, MiniTool will explain the definition of JVM and provide a full download/install guide.

Java, developed by Oracle Corporation, is one of the most popular programming languages that is widely used for desktop computers, android development, games, and other development tasks. However, many users find there are different components of the Java program like JRE, JDK, and JVM.

What is JVM? Is JVM the same as JDK and JRE? How to download and install Java Virtual Machine for Windows 10/8/7? Keep reading the content below.

What Is a Java Virtual Machine (JVM)

Java Virtual Machine, also known as JVM, is a virtual environment that allows a computer to run Java programs written in other programming languages that are translated to Java bytecode. That is to say, JVM works as an interpreter that can load, verify, and executes Java bytecode.

In addition, JVM is also responsible for converting Java bytecode to machine-specific code. In addition, it is platform-dependent and can perform many tasks like memory management and security. Java Virtual Machine mainly consists of the following 3 components or subsystems.

• Runtime Data Areas: It is responsible for providing memory to store bytecode, objects, parameters, local variables, return values, and intermediate results of computations. It mainly contains PC register sets, method areas, stack areas, and threads.
• Class Loader Subsystem: It is an essential core of the JVM and can be used for loading/reading/linking the “. Class” files and saving the Java bytecode in the JVM method area.
• Execution Engine: It is the central component of the JVM and can communicate with various memory areas of the JVM. It executes the bytecode assigned to the Runtime Data Areas in JVM via the Class Loader.

What is JVM? Now, I believe that you already have known the answer. Let’s see where to get the Java Virtual Machine download pack.

Is JVM the Same as JRE and JDK

Is JVM the same as JRE and JDK? A lot of users are confused about the difference between JRE vs JDK vs JVM. JRE (Java Runtime Environment) is a software distribution that provides an environment for a Java program or app using the Java command. It is mainly used for those who only want to execute Java programs that are end-users of the system.

JDK is short for Java Development Kit which is a software development environment used for developing and executing Java programs, while JVM is responsible for loading, verifying, and executing Java bytecode. In addition, JVM is necessary for both JDK and JRE and Java programs won’t run without it. If the JVM component of Java programs gets corrupted or missing, you may encounter some errors like “a Java Virtual Machine is required” and “Minecraft could not create the java virtual machine”.
