如何给eclipse更多的内存比512M？ [英] How can I give eclipse more memory than 512M?

问题描述

我有以下设置，但是当我把1024和1024全部替换为1024时，eclipse将不会启动。我的eclipse JVM可以有超过512M的内存吗？

I have following setup, but when I put 1024 and replace all 512 with 1024, then eclipse won't start at all. How can I have more than 512M memory for my eclipse JVM?

-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-product
com.springsource.sts.ide
--launcher.XXMaxPermSize
512M
-vm
C:\Program Files (x86)\Java\jdk1.6.0_18\bin\javaw 
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms512m
-Xmx512m
-XX:MaxPermSize=512m

推荐答案

我遇到了很多问题，试图让Eclipse接受尽可能多的内存我希望它能够使用（例如2到4个演出）。

I've had a lot of problems trying to get Eclipse to accept as much memory as I'd like it to be able to use (between 2 and 4 gigs for example).

打开 eclipse.ini 在Eclipse安装目录中。
您应该可以在 -vmargs 之后更改内存大小，最多为1024个，但没有问题，最大值取决于你的系统。这是我的Linux盒子上的那部分：

Open eclipse.ini in the Eclipse installation directory. You should be able to change the memory sizes after -vmargs up to 1024 without a problem up to some maximum value that's dependent on your system. Here's that section on my Linux box:

-vmargs
-Dosgi.requiredJavaVersion=1.5
-XX:MaxPermSize=512m
-Xms512m
-Xmx1024m

这里是我的Windows框：

And here's that section on my Windows box:

-vmargs
-Xms256m
-Xmx1024m

但是，我没有设置高于1024兆的。如果有人知道如何做这个工作，我很想知道。

But, I've failed at setting it higher than 1024 megs. If anybody knows how to make that work, I'd love to know.

编辑：32位版本的juno似乎不接受Xmx1024m，64位版本接受2048。

EDIT: 32bit version of juno seems to not accept more than Xmx1024m where the 64 bit version accept 2048.

编辑：Nick的帖子包含一些很棒的链接，可以解释两个不同的东西：

EDIT: Nick's post contains some great links that explain two different things:

• 问题在于很大程度上取决于您的系统和可用的连续可用内存量，


• 通过使用javaw.exe（在Windows上），您可能可以获得更大的分配的内存块。

• The problem is largely dependent on your system and the amount of contiguous free memory available, and
• By using javaw.exe (on Windows), you may be able to get a larger allocated block of memory.

I有8个演出的Ram，并且不能将 -Xmx 设置为超过1024 megs的ram，即使最少的程序加载，并且Windows / linux在4之间报告和5公斤的免费公羊。

I have 8 gigs of Ram and can't set -Xmx to more than 1024 megs of ram, even when a minimal amount of programs are loaded and both windows/linux report between 4 and 5 gigs of free ram.
