Eclipse Juno在编辑器中切换选项卡的速度很慢 [英] Eclipse Juno slow to switch tabs in editor

问题描述

在OSX 10.8.2 Mountain Lion的Eclipse Juno SR1中，Java版本1.6.0_37，启动后的一段时间，只需在要编辑的源文件的标签之间切换就变得非常慢。 CPU显示为100％，编辑器会冻结几秒钟，然后才会显示新的标签内容。

在阅读有关问题的时候，我编辑了我的eclipse.ini，

   -  launcher.XXMaxPermSize 2768M 
 -XX：MaxPermSize = 2768M 
 -Xms440m 
 -Xmx2512m 
  

根据 http://wiki.eclipse.org/ ，而这仅仅是影响到现在重新启动Eclipse需要更长时间才能让问题重新开始。

$ b $我不敢相信在SATAIII SSD的机器上，一个i5处理器和8GB的ram在文本编辑器中切换标签可能会很慢。还有什么我可以试试吗？

解决方案

Juno和Juno SR1在打开，关闭和切换编辑器时出现严重的性能问题。 / p>

Eclipse社区已经修复了很多性能问题在即将推出的Juno SR2和Kepler M4中。您可以安装Juno的维护版本来尝试。

In Eclipse Juno SR1 on OSX 10.8.2 Mountain Lion, Java version "1.6.0_37", a while after startup it becomes very slow to simply switch between tabs for source files being edited. The CPU goes to 100% and the editor freezes for several seconds before the new tab content is shown.

Upon reading about the problem I edited my eclipse.ini to have:

--launcher.XXMaxPermSize 2768M
-XX:MaxPermSize=2768M
-Xms440m
-Xmx2512m

As advised at http://wiki.eclipse.org/, and this only had the effect that now it takes longer after I restart Eclipse for the problem to start happening again.

I can't believe that on a machine with a SATAIII SSD, an i5 processor and 8GB of ram that switching tabs in a text editor could be so slow. Is there anything else I can try?

解决方案

Juno and Juno SR1 have serious performance issue when open, close and switch editors.

Eclipse community has fixed lots of performance issues in upcoming Juno SR2 and Kepler M4. You can install maintenance build of Juno to have a try.
