Eclipse 3.4（Ganymede）的内存使用率明显高于3.2？ [英] Is Eclipse 3.4 (Ganymede) memory usage significantly higher than 3.2?

问题描述

我很高兴地使用Eclipse 3.2（或者像一个可以使用Eclipse一样快乐），因为一个被遗忘的原因，我决定升级到3.4。我主要使用PyDev，Aptana和Subclipse，非常少的Java开发。

我注意到3.4倾向于真正给我的笔记本电脑疝气比3.2（vista ，core2duo，2G）。内存使用率3.4实际上高于3.2，如果是这样的方法来减少它？

编辑：我尝试禁用插件（我没有太多启用）并使用jvm监视器;后者是有趣的，但我无法弄清楚如何以任何实用的方式使用信息。我仍然无法减少其内存占用。我也注意到，每隔一段时间，Eclipse只会挂起约30秒，然后神奇回来。

解决方案

选项，我设法将内存限制为700Mo（这相当高，但仍然可以用我的2 Go）

  vmargs 
 -Xms128m 
 -Xmx384m 
 -Xssv2m 
 -XX：PermSize = 128m 
 -XX：MaxPermSize = 128m 
 -XX：CompileThreshold = 5 
 -XX：+ UseParallelGC 
 -Dcom.sun.management.jmxremote 
  

还要考虑推出

  C：\ [jdk1.6.0_0x路径] \bin\jconsole.exe 
  

并选择'Connection / New connection /'eclipse'来监视eclipse使用的内存

（这就是为什么我使用'-Dcom.sun.management.jmxremote'）

其他选项可用 here 。

I was happily using Eclipse 3.2 (or as happy as one can be using Eclipse) when for a forgotten reason I decided to upgrade to 3.4. I'm primarily using PyDev, Aptana, and Subclipse, very little Java development.

I've noticed 3.4 tends to really give my laptop a hernia compared to 3.2 (vista, core2duo, 2G). Is memory usage on 3.4 actually higher than on 3.2, and if so is there a way to reduce it?

EDIT: I tried disabling plugins (I didn't have much enabled anyway) and used the jvm monitor; the latter was interesting but I couldn't figure out how to use the info in any practical way. I'm still not able to reduce its memory footprint. I've also noticed every once in a while Eclipse just hangs for ~30 seconds, then magically comes back.

解决方案

With those options, I manage to limit the memory used to 700Mo (which is quite high, but still workable with my 2 Go)

-vmargs
-Xms128m
-Xmx384m
-Xssv2m
-XX:PermSize=128m
-XX:MaxPermSize=128m
-XX:CompileThreshold=5
-XX:+UseParallelGC
-Dcom.sun.management.jmxremote

And consider also to launch

C:\[jdk1.6.0_0x path]\bin\jconsole.exe

And choose 'Connection / New connection / 'eclipse' to monitor the memory used by eclipse
(which is why I use '-Dcom.sun.management.jmxremote')

Other options are available here.
