Max value of Xmx and Xms in Eclipse?
提问by Lieven Cardoen
Now my settings for these in the ini file are:
现在我在 ini 文件中的这些设置是：
-Xms768M -Xmx1024M
-Xms768M -Xmx1024M
When setting them higher, eclipse doesn't start anymore... Is there a way to increase these values without eclipse crashing?
将它们设置得更高时，日食不再启动......有没有办法增加这些值而不使日食崩溃？

The maximum values do not depend on Eclipse, it depends on your OS (and obviously on the physical memory available).
最大值不取决于 Eclipse，它取决于您的操作系统（显然还取决于可用的物理内存）。
You may want to take a look at this question: Max amount of memory per java process in Windows?
您可能想看看这个问题：Windows 中每个 Java 进程的最大内存量？

I am guessing you are using a 32 bit eclipse with 32 bit JVM. It wont allow heapsize above what you have specified.
我猜你正在使用带有 32 位 JVM 的 32 位 eclipse。它不允许堆大小超过您指定的大小。
Using a 64-bit Eclipse with a 64-bit JVM helps you to start up eclipse with much larger memory. (I am starting with -Xms1024m -Xmx4000m)
将 64 位 Eclipse 与 64 位 JVM 一起使用可帮助您以更大的内存启动 Eclipse。（我从 -Xms1024m -Xmx4000m 开始）

Why do you need -Xms768 (small heap must be at least 768...)?
为什么需要-Xms768（小堆必须至少768...）？
That means any java process (search in eclipse) will start with 768m memory allocated, doesn't that? That is why your eclipse isn't able to start properly.
这意味着任何 java 进程（在 eclipse 中搜索）都将从分配的 768m 内存开始，不是吗？这就是您的日食无法正常启动的原因。
Try -Xms16 -Xmx2048m, for instance.
例如，尝试 -Xms16 -Xmx2048m。

I have tried the following config for eclipse.ini:
我已经为 eclipse.ini 尝试了以下配置：
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
1024M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
1024m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms128m
-Xmx2048m
Now eclipse performance is about 2 times faster then before.
现在 eclipse 的性能比以前快了大约 2 倍。
