不可低估的是拥有一台快速的机器。16-32 GB的RAM, SSD和一个不错的处理器……who0o0om你走了。

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.

在特殊情况下，性能差可能是由于损坏了h2或nwire数据库。有关更多信息，请阅读加速Eclipse PDT和nWire的五个技巧。

在我工作的地方，我们依赖虚拟机来运行Debian。出于测试目的，我已经在VM上安装了另一个Eclipse版本，但如果我运行的是另一个Eclipse版本，有时会产生冲突。有一个两个Eclipse版本共享的共享文件夹。有一次我不小心让Debian Eclipse安装在后台运行，结果导致数据库文件损坏。

禁用标签装饰可以获得另一种性能提升 (Windows ->首选项;概述->外观->标签装饰) 在启动时禁用未使用的功能 (Windows ->首选项;一般->启动和关闭)。

您还可以根据JVM选择不同的垃圾收集策略来获得额外的性能。

如果你厌倦了重启周期，你可以使用ZeroTurnaround的JavaRebel。这将缩短重启服务器/客户端的时间。

我给了它大量的内存(在启动它的命令中添加一个- xmx开关)，并尽量避免退出和重新启动它——我发现最严重的延迟是在启动时，所以给它大量的RAM可以让我在崩溃之前保持更长的时间。

还有一件事可以在Windows和Linux上加速Eclipse——将JVM放在RAM磁盘中。

对于Windows，您可以使用Qsoft的商用RAM磁盘驱动程序。

对于Linux，可以使用Internet上许多文章中描述的任何一种方法。重要的是要为RAM磁盘提供比JVM大小大10%的额外空间。

来看看。这真的很重要。
