1. Overview
1.概述
IntelliJ IDEA is a popular integrated development environment (IDE) with robust features and capabilities. However, as projects become complex, we may encounter scenarios in which the amount of memory IntelliJ allocates by default is insufficient for our needs.
IntelliJ IDEA 是一种流行的集成开发环境 (IDE)，具有强大的特性和功能。但是，随着项目变得复杂，我们可能会遇到 IntelliJ 默认分配的内存量不足以满足我们需求的情况。
In this tutorial, we’ll learn to increase the memory size limit on IntelliJ IDEA. Overall, this ensures a smoother and more responsive development experience.
在本教程中，我们将学习如何增加 IntelliJ IDEA 的内存大小限制。总之，这将确保更流畅、反应更灵敏的开发体验。
2. Adjusting the Memory Settings
2.调整内存设置
Adjusting memory settings involves modifying the configuration to allocate sufficient memory resources for the Java Virtual Machine (JVM) to operate efficiently. This process is crucial when working on large projects or dealing with memory-intensive tasks.
调整内存设置涉及修改配置，以便为Java 虚拟机 (JVM) 分配足够的内存资源，使其高效运行。在处理大型项目或内存密集型任务时，这一过程至关重要。
Let’s now go through the step-by-step process of adjusting the memory allocation.
现在，让我们一步步来调整 内存分配。
2.1. Updating the idea.vmoptions File
2.1.更新 idea.vmoptions 文件
The first step is to determine the installation directory of the IntelliJ IDEA application on the machine. Further, we’ll locate the idea.vmoptions file inside the installation directory. This file is generally present inside the bin folder.
第一步是确定机器上 IntelliJ IDEA 应用程序的安装目录。然后，我们将在安装目录中找到 idea.vmoptions 文件。该文件通常位于 bin 文件夹中。
Once we’ve located the idea.vmoptions file, let’s now adjust the JVM parameters -Xms (minimum heap size) and -Xmx (maximum heap size) to allocate more memory:
找到 idea.vmoptions 文件后，让我们调整 JVM参数 -Xms（最小堆大小）和 -Xmx（最大堆大小），以分配更多内存：
The above settings will allocate an initial heap size of 256 megabytes and a maximum heap size of 2048 megabytes. Make sure to adjust these values based on the project’s requirements and available system resources.
上述设置将分配 256 兆字节的初始堆大小和 2048 兆字节的最大堆大小。请务必根据项目要求和可用系统资源调整这些值。
At last, save the changes and restart IntelliJ IDEA to apply the new memory settings.
最后，保存更改并重启 IntelliJ IDEA 以应用新的内存设置。
2.2. Updating Memory Settings from the UI
2.2.从用户界面更新内存设置
Alternatively, we can also modify memory settings from the IntelliJ UI, using the “Help” ->“Change Memory Settings” menu option:
另外，我们还可以使用 “帮助”->“更改内存设置” 菜单选项，在 IntelliJ UI 中修改内存设置：
Using this method, we can only update the maximum heap size. Moreover, all the changes made from the UI will be saved to the idea.vmoptions file:
使用此方法，我们只能更新最大堆大小。此外，从用户界面进行的所有更改都将保存到 idea.vmoptions 文件中：
At last, we need to restart IntelliJ IDEA for our changes to take effect. Click on the “Save and Restart” button.
最后，我们需要重启 IntelliJ IDEA，以使更改生效。单击 “保存并重新启动” 按钮。
3. Monitor Memory Usage
3.监控内存使用情况
After updating the allocated memory to a desired value, monitoring memory usage is essential to ensure optimal performance. IntelliJ IDEA provides a way to track memory consumption to help developers identify potential issues.
将分配的内存更新为理想值后，监控内存使用情况对于确保最佳性能至关重要。IntelliJ IDEA 提供了一种跟踪内存消耗的方法，可帮助开发人员识别潜在问题。
Right-click on the bottom right part of the taskbar. Select the “Memory Indicator” option to enable the memory indicator:
右键单击任务栏右下方。选择“内存指示器”选项，启用内存指示器：
After enabling it, we can easily monitor memory consumption by heap and JVM. Hover over the bottom right corner of the status bar to view the breakdown:
启用该功能后，我们可以轻松监控堆和 JVM 的内存消耗情况。将鼠标悬停在状态栏右下角，即可查看细目：
Alternatively, we can double-press the “Shift” key and search for the “Memory Indicator”.
或者，我们可以双击“Shift”键，然后搜索“内存指示器”。
4. Conclusion
4.结论
This article discussed the importance of memory allocation in a development environment and how to increase it for IntelliJ IDEA. Firstly, we updated the memory using the configuration file. Further, we learned to update it using IntelliJ’s UI.
本文讨论了开发环境中内存分配的重要性，以及如何增加 IntelliJ IDEA 的内存分配。首先，我们使用配置文件更新了内存。此外，我们还学习了如何使用 IntelliJ 的用户界面更新内存。
Remember to regularly evaluate the project’s requirements and adjust memory settings accordingly.
切记定期评估项目要求并相应调整内存设置。
