如果Eclipse运行缓慢，我遵循以下几个步骤:

Any unused plugins installed in Eclipse, should uninstall them. -- Few plugins makes a lot much weight to Eclipse. Open current working project and close the remaining project. If there is any any dependency among them, just open while running. If all are Maven projects, then with miner local change in pom files, you can make them individual projects also. If you are working on independent projects, then always work on any one project in a workspace. Don't keep multiple projects in single workspace. Change the type filters. It facilitates to specify particular packages to refer always. As per my experience, don't change memory JVM parameters. It causes a lot of unknown issues except when you have sound knowledge of JVM parameters. Un-check auto build always. Particulary, Maven project's auto build is useless. Close all the files opened, just open current working files. Use Go Into Work sets. Instead of complete workbench. Most of the components of your application you can implement and test in standalone also. Learn how to run in standalone without need of server deploy, this makes your work simple and fast. -- Recently, I worked on hibernate entities for my project, two days, I did on server. i.e. I changed in entities and again build and deployed on the server, it killing it all my time. So, then I created a simple JPA standalone application, and I completed my work very fast.

转到Windows ->首选项->验证，取消选中任何你不想要或不需要的验证器。

对于Eclipse 3.7，您使用Windows ->首选项->通用->启动和关机。

在eclipse.ini文件中添加-Xverify:none。

它将大大缩短Eclipse启动时间(对我来说是50%，如果不是更多的话)。这将告诉VM不要验证它正在加载的所有.class文件。

考虑一下:永远不要在生产系统中禁用字节码验证 (如评论所述)

试试这些。有两种方法。

第一个过程

参考这篇文章。

http://www.javacodegeeks.com/2014/06/the-real-way-to-make-eclipse-run-faster-on-ubuntu.html

第二个过程。

在终端执行命令。

ramdisk

为Ubuntu获得更好的性能和更快的响应。

Ramdisk是系统内存的一部分。Ubuntu默认使用物理内存(RAM)的一半作为ramdisk，并将其挂载到RAM上

/dev/shm

，它可以像普通磁盘空间一样使用(创建文件和文件夹，并以更好的性能操作它们，而不是将它们存储在硬盘上)。如果ramdisk使用了超过一半的RAM，则数据将被转移到交换空间。如果ramdisk使用更少的内存，剩余的内存仍然可以做RAM正在做的事情。

设置ramdisk上限

如上所述，默认情况下，ramdisk可以使用一半的RAM。如果您想更改上限，请执行以下步骤:

使用您最喜欢的编辑器编辑/etc/fstab: Gksudo gedit /etc/fstab .使用实例 找到这一行并更改它使其看起来像这样(如果不存在则添加这一行，并将512M更改为您喜欢的内容): tmpfs /dev/shm tmpfs默认值，size=512M 0 0 重启或重新挂载 /dev/shm

将/tmp挂载到ramdisk上

为了便于使用，可以将目录挂载到

/dev/shm

通过以下命令:

mkdir /dev/shm/tmp

chmod 1777 /dev/shm/tmp

绑定/dev/shm/tmp /tmp

谢谢你的提示。 上面提到的这些选择对我帮助很大:

窗口:

增加内存&关于我在eclipse.ini中更新的Java版本:

-Dosgi.requiredJavaVersion=1.6
-Xms512m
-Xmx512m
-XX:PermSize=512m
-XX:MaxPermSize=512M
-Xverify:none

此外，由于我们正在优化速度，因此将-Xms设置为与-Xmx相同的值将使JVM以允许使用的最大内存量启动。

Linux / Ubuntu:

使用

update-alternatives --config java

Windows用户:

If you go to Task Manager, choose the eclipse application, and click on the little arrow next to it, you will usually just see one sub-process appear below "eclipse.exe". However, in my case, if you have multiple instances of "Java Platform SE Binary", then end all of them. For some reason, I had three of these running in the background, even though I wasn't currently running any projects. Nevertheless, this will boost performance back to the way it likely was when you first installed eclipse on your computer.

如果更改后您不能再运行项目，那么尝试重新启动eclipse。
