与Oracle J2SE 1.7相对应的JVM选项，用于Eclipse'kepler'4.3 [英] Equivalent JVM options with Oracle J2SE 1.7, for Eclipse 'kepler' 4.3
问题描述
尝试在运行64位基于Debian的低功率上网本(双核1.66MHz Atom N455)上提高Eclipse"Kepler" rel-4.3 IDE的性能.
Trying to improve Eclipse 'Kepler' rel-4.3 IDE's performance on a rather low-powered Netbook (dual-core 1.66MHz Atom N455), running 64-bit Debian based distro.
找到了以下两个之前的问题( q1 ， q2 )，并尝试了几种组合.
Found the following 2 previous questions (q1, q2) on SE, and tried few combinations.
$ java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)
与默认的eclipse.ini以及在IcedTea中使用OpenJDK 6相比，我为eclipse.ini采用了以下设置，而不是更快地启动和操作，但感觉有些放慢了.因此，问题是，是否建议使用任何建议的操作或与Oracle Jave SE 1.7冲突?
Adopting the following settings for eclipse.ini, instead of faster startup and operation, I felt some slow-down instead, compared to the default eclipse.ini and use of OpenJDK 6 with IcedTea. So the question is, are any of the suggested operations known to be deprecated or conflict with Oracle Jave SE 1.7
尝试了新的eclipse.ini:

-nosplash

推荐答案
我遇到了同样的问题.我认为这更多的是您的Java版本不建议使用的功能"问题，因为它将大多数命令传递给了Java.开普勒帮助文件并没有具体说明您和我正在传递的许多命令，所以这就是我的想法.
I'm running into the same thing. I think it's more a "what's deprecated in your Java version" issue since it's passing most of the commands to Java. The kepler help file doesn't get to specific with a lot of the commands you and I are passing so that's what I'm thinking.
我要说的一件事是在快速阅读Interweb之后，我认为这两个不能同时使用，但是我不知道.-XX:+ UseConcMarkSweepGC-XX:+ UseParNewGC
one thing I will say is after speed reading the Interweb I think these 2 can't be used at the same time but I dunno. -XX:+UseConcMarkSweepGC -XX:+UseParNewGC
我只有我的第二个
这是我在上面阅读的地方 http://www.fasterj.com/articles/oraclecollectors1.shtml
here's where I was reading on it http://www.fasterj.com/articles/oraclecollectors1.shtml
好吧，再次阅读它似乎可以同时使用这两个
well, reading it again it looks like you can use both of those 2
也许在这里 http://docs.oracle.com/javase/7/docs/technotes/tools/solaris/java.html
