Best memory settings for eclipse 4.2 (STS 3.1) on Windows 7 64 bit?
提问by jorrebor
I apoligize in advance if this question is indeed too subjective as SO warns me.
如果这个问题确实像 SO 警告我的那样过于主观，我会提前道歉。
My workstation has 8 gb of ram and runs windows 7 64 bit. I use the Spring tool Suite (3.1) but as soon as i am starting to open and modify the spring config (.xml) files, STS becomes incredibly slow.
我的工作站有 8 GB 内存并运行 Windows 7 64 位。我使用 Spring 工具套件 (3.1)，但是一旦我开始打开和修改 spring 配置 (.xml) 文件，STS 就会变得非常慢。
I already tried switching off "build automatically" and to increase memory settings but no luck.
我已经尝试关闭“自动构建”并增加内存设置但没有运气。
How should i change my .ini ? this is what i have set now:
我应该如何更改我的 .ini ？这是我现在设置的：
-vm

-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms512m
-Xmx2048m
-XX:MaxPermSize=512m
My collageu running the same project in IntelliJ, has no problems.
我的同事在 IntelliJ 中运行相同的项目，没有问题。
Thank you!
谢谢！

A 2gb heap is plenty for eclipse, I use it myself. My suspicion is the culprit is Eclipse 4.2 Juno. It has very well documented performance issues. There is a hidden 3.8 Juno version on the eclipse download site. It has all the same features that 4.2 Juno has but uses the old UI components which are more stable and performant.
一个 2GB 的堆对于 eclipse 来说已经足够了，我自己使用它。我怀疑罪魁祸首是 Eclipse 4.2 Juno。它有很好的记录性能问题。eclipse 下载站点上有一个隐藏的 3.8 Juno 版本。它具有与 4.2 Juno 相同的所有功能，但使用更稳定和性能更好的旧 UI 组件。
