Eclipse Juno (4.2) 中的缓慢

Slowness in Eclipse Juno (4.2)

提问by seagoj

I've had some issues with slowness switching tabs in Eclipse 4.2 Juno and was hoping someone might have some answers. The original delay was about 10 seconds which dropped to 2-4 once I specified the java vm in the eclipse.ini file, but that's still slower than I think it should be. I've uninstalled all the addons that I thought might be offending and listed the active ones below and I believe the system to be more than adequate, but listed the specs anyway. Thanks for any help you could give me.

我在 Eclipse 4.2 Juno 中缓慢切换选项卡时遇到了一些问题，希望有人能得到一些答案。最初的延迟大约是 10 秒，一旦我在 eclipse.ini 文件中指定了 java vm，它就会下降到 2-4 秒，但这仍然比我想象的要慢。我已经卸载了所有我认为可能有问题的插件，并在下面列出了活跃的插件，我相信系统已经足够了，但无论如何都列出了规格。感谢您能给我的任何帮助。

• disable unneeded validations (Window -> Preferences -> Validations).
• limit the number of visible validations (Problems View -> Configure Content)
• increase memory for eclipse in eclipse.ini as you did
• enable virtual memory mapping for git
• use the classic theme

• 禁用不需要的验证 ( Window -> Preferences -> Validations)。
• 限制可见验证的数量 ( Problems View -> Configure Content)
• 像您一样在 eclipse.ini 中增加 eclipse 的内存
• 为 git 启用虚拟内存映射
• 使用经典主题

all together gave my Juno a big speed boost :)

I had the same problem, I upgraded to Eclipse Juno 4.2.2and my system: Intel Core 2 Quad Q9550 2.83Ghz 8,00 GB RAM Windows 7 Ultimate x64. I also use GIT.

我遇到了同样的问题，我升级到Eclipse Juno 4.2.2和我的系统：Intel Core 2 Quad Q9550 2.83Ghz 8,00 GB RAM Windows 7 Ultimate x64。我也使用GIT。

When I pressed the right mouse button on my projectit took a lot of time (~ 40s) before I could do anything.

当我在我的项目上按下鼠标右键时，我花了很多时间（大约 40 秒）才能做任何事情。

That was until I ran "git gc"on my Linux server (different system) with the following result:

直到我在Linux 服务器（不同系统）上运行“git gc”，结果如下：

• Counting objects: 6454, done.
• Delta compression using up to 8 threads.
• Compressing objects: 100% (5983/5983), done.
• Writing objects: 100% (6454/6454), done.
• Total 6454 (delta 1785), reused 0 (delta 0).

• 计数对象：6454，完成。
• 使用多达 8 个线程的增量压缩。
• 压缩对象：100% (5983/5983)，完成。
• 写入对象：100% (6454/6454)，完成。
• 总计 6454（增量 1785），重用 0（增量 0）。

After that I refreshed my project and since then the right mouse button actionresponse is instant.

之后我刷新了我的项目，从那时起鼠标右键动作响应是即时的。

I hope this helps anyone, I just had to share this with you.

我希望这对任何人都有帮助，我只是不得不与您分享。
