加速IntelliJ-Idea [英] Speedup IntelliJ-Idea

问题描述

我正在使用intelliJ进行Scala开发并且上周获得了 8 GB 的新RAM，所以我想：时间使用它。我检查了我的任务管理器，发现使用 ~250mb 的intelliJ。从eclipse我知道调整JVM选项有助于提高速度，所以我用Google搜索...

I'm using intelliJ for Scala development and got 8 GB of new RAM last week, so I thought: time to use it. I checked my task manager and found intelliJ using ~250mb. From eclipse I knew that tweaking JVM options helped a lot in improving speed, so I googled ...

并找到这个用于OS X
我找不到JVM选项立即，所以我开始调整 Xmx。在1 GB时，我意识到它不再启动了。我检查了intelliJ java版本，发现它已经过时了，32位。

and found this one for OS X I couldn't find the JVM option immediately, so I started tweaking Xmx. At 1 GB, I realized it doesn't start any more. I checked the intelliJ java version, found it's outdated and 32bit.

因此，为了使用您当前的JDK和 64位，您必须将链接更改为：

So in order to use your current JDK and 64 bit you have to change your link to from:

IntelliJ IDEA Community Edition 10.0.2\bin\idea.exe

到

IntelliJ IDEA Community Edition 10.0.2\bin\idea.BAT

并调整开始

bat会查找 JDK_HOME 并立即使用64位。

The bat looks for JDK_HOME and uses 64bit now.

我当前的 VM选项，它位于

...\IntelliJ IDEA Community Edition 10.0.2\bin\idea.exe.vmoptions

-Xms512m
-Xmx1024m
-XX:MaxPermSize=512m
-ea
-server
-XX:+DoEscapeAnalysis
-XX:+UseCompressedOops
-XX:+UnlockExperimentalVMOptions
-XX:+UseParallelGC

的 -XX：+ UseParallelGC ，你可以使用 -XX：+ UseConcMarkSweepGC ，

桌面应用程序的可接受选择，
但我最近改为吞吐量
收藏家。因为使用
快速机器和足够小的堆，
你有快速暂停，更多吞吐量
并且没有碎片问题
（ijuma。#scala）

the accepted choice for desktop apps, but I have changed to the throughput collector recently. because with a fast machine and a small enough heap, you have quick pauses, more throughput and no issues with fragmentation (ijuma. #scala)

更改：

-XX:+UseConcMarkSweepGC //removed
// removed, because not needed with the lastest JVM.
    -XX:+UnlockExperimentalVMOptions
    -XX:+DoEscapeAnalysis
    -XX:+UseCompressedOops

我现在坚持这些选择。我真的很想知道你的经历。

I'll stick to these options for now. I would really like to know your experience with it.

哪种选择最适合您？
如何通过 .bat 运行intelliJ时隐藏此cmd窗口？ ：）

Which options work best for you? How do I hide this cmd window while running intelliJ through the .bat? :)

顺便说一句，这是调整智能。基本上它在 p.20 / 21 上说关闭Windows恢复和系统dirs的防病毒。

By the way, here's another link for tuning intelliJ. Basically it says on p.20/21 to turn off windows restore and antivirus for system dirs.

另一种加速intelliJ的方法是将intellij系统文件夹放在 ramdrive （感谢OlegYch | h）。

Another way to speed up intelliJ is to put intellij system folder on ramdrive (thanks OlegYch|h).

from idea.properties 
idea.system.path=${idea.home}/.IntelliJIdea/system

参见< a href =https://superuser.com/questions/34388/whats-the-best-ramdisk-for-windows> Win 7 64位RAM驱动器的超级用户或这一个。
1 GB对我来说似乎没问题。

See Superuser for Win 7 64bit RAM Drive or this one. 1 GB seems fine for me.

朋友给我的另一个提示是从防病毒软件中排除项目目录（扫描访问）

Another hint a friend gave me is to exclude the project directories from your antivirus (scan on access)

关于调整Eclipse有类似的帖子：

There are similar posts regarding tuning Eclipse:

• Eclipse Helios 3.6


• Eclipse Juno 4.2


• 将JVM指定为用启动Eclipse

• Eclipse Helios 3.6
• Eclipse Juno 4.2
• Specify the JVM to start Eclipse with

推荐答案

这个组合在我在小牛队中运行的Intellij13上非常有效：

This combination works great on my Intellij13 running in Mavericks:
