How can I give eclipse more memory than 512M?
提问by newbie
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?
我有以下设置，但是当我放入 1024 并将所有 512 替换为 1024 时，eclipse 根本无法启动。我的 Eclipse JVM 如何拥有超过 512M 的内存？
-startup

--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-product

512M

-vmargs

-Xms512m
-Xmx512m
-XX:MaxPermSize=512m

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).
我在试图让 Eclipse 接受尽可能多的内存时遇到了很多问题（例如，在 2 到 4 个演出之间）。
Open eclipse.iniin the Eclipse installation directory.
You should be able to change the memory sizes after -vmargsup to 1024 without a problemup to some maximum value that's dependent on your system. Here's that section on my Linux box:
eclipse.ini在 Eclipse 安装目录中打开。您应该能够在之后更改内存大小-vmargs高达 1024 没有问题最多取决于您的系统的某个最大值。这是我的 Linux 机器上的那部分：
-vmargs
-Dosgi.requiredJavaVersion=1.5
-XX:MaxPermSize=512m
-Xms512m
-Xmx1024m
And here's that section on my Windows box:
这是我的 Windows 盒子上的那个部分：
-vmargs
-Xms256m
-Xmx1024m
But, I've failed at setting it higher than 1024 megs. If anybody knows how to make that work, I'd love to know.
但是，我未能将其设置为高于 1024 megs。如果有人知道如何进行这项工作，我很想知道。
EDIT: 32bit version of juno seems to not accept more than Xmx1024m where the 64 bit version accept 2048.
编辑：juno 的 32 位版本似乎不接受超过 Xmx1024m 的 64 位版本接受 2048。
EDIT: Nick's post contains some great links that explain two different things:
编辑：尼克的帖子包含一些很好的链接，解释了两个不同的事情：
- The problem is largely dependent on your systemand 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.
- 该问题在很大程度上取决于您的系统和可用的连续可用内存量，并且
- 通过使用 javaw.exe（在 Windows 上），您可以获得更大的分配内存块。
I have 8 gigs of Ram and can't set -Xmxto 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.
我有 8 场内存，并且不能设置-Xmx为超过 1024 兆内存，即使加载了最少量的程序并且 windows/linux 都报告了 4 到 5 场可用内存。

Here is how i increased the memory allocation of eclipse Juno:
以下是我增加 eclipse Juno 内存分配的方法：
I have a total of 4GB on my system and when im working on eclipse, i dont run any other heavy softwares along side it. So I allocated 2Gb.
我的系统上总共有 4GB 空间，当我在 eclipse 上工作时，我不会在它旁边运行任何其他重型软件。所以我分配了2Gb。
The thing i noticed is that the difference between min and max values should be of 512. The next value should be let say 2048 min + 512 = 2560max
我注意到的是最小值和最大值之间的差异应该是 512。下一个值应该是 2048 min + 512 = 2560max
Here is the heap value inside eclipse after setting -Xms2048m -Xmx2560m:
这是设置后eclipse内部的堆值-Xms2048m -Xmx2560m：

More or less, keep trying smaller amounts til it works, that's your max.
或多或少，继续尝试较小的量直到它起作用，这是你的最大值。

You can copy this to your eclipse.inifile to have 1024M:
您可以将其复制到您的eclipse.ini文件中以获得 1024M：
-clean -showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-Xms512m
-Xmx1024m
-XX:PermSize=128m
-XX:MaxPermSize=256m
回答by elduff
I don't think you need to change the MaxPermSize to 1024m. This works for me:
我认为您不需要将 MaxPermSize 更改为 1024m。这对我有用：
-startup
plugins/org.eclipse.equinox.launcher_1.0.200.v20090520.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-product
org.eclipse.epp.package.jee.product
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms256m
-Xmx1024m
-XX:PermSize=64m
-XX:MaxPermSize=128m

While working on an enterprise project in STS (heavily Eclipse based) I was crashing constantly and STS plateaued at around 1GB of RAM usage. I couldn't add new .war files to my local tomcat server and after deleting the tomcat folder to re-add it, found I couldn't re-add it either. Essentially almost anything that required a new popup besides the main menus was causing STS to freeze up.
在 STS（主要基于 Eclipse）中从事企业项目时，我不断崩溃，STS 稳定在大约 1GB 的 RAM 使用量。我无法将新的 .war 文件添加到我的本地 tomcat 服务器，并且在删除 tomcat 文件夹以重新添加它后，发现我也无法重新添加它。基本上，除了主菜单之外，几乎所有需要新弹出窗口的东西都会导致 STS 冻结。
I edited the STS.ini (your Eclipse.ini can be configured similarly) to:
我将 STS.ini（您的 Eclipse.ini 可以类似配置）编辑为：
--launcher.XXMaxPermSize 1024M -vmargs -Xms1536m -Xmx2048m -XX:MaxPermSize=1024m
--launcher.XXMaxPermSize 1024M -vmargs -Xms1536m -Xmx2048m -XX:MaxPermSize=1024m
Rebooted STS immediately and saw it plateau at about 1.5 gigs before finally not crashing
立即重新启动 STS 并看到它在大约 1.5 gigs 时处于稳定状态，然后最终没有崩溃

Configuring this worked for me: -vmargs -Xms1536m -Xmx2048m -XX:MaxPermSize=1024m on Eclipse Java Photon June 2018
配置这个对我有用：-vmargs -Xms1536m -Xmx2048m -XX:MaxPermSize=1024m on Eclipse Java Photon June 2018
Running Windows 10, 8 GB ram and 64 bit. You can extend -Xmx2048 -XX:MaxpermSize= 1024m to 4096m too, if your computer has good ram.Mine worked well.
运行 Windows 10、8 GB 内存和 64 位。您也可以将 -Xmx2048 -XX:MaxpermSize= 1024m 扩展到 4096m，如果您的计算机具有良好的内存。我的运行良好。
