What does "Computing additional info" mean?
提问by JesperE
Eclipse Helios periodically starts running a job which displays "Computing additional info". During this time, Eclipse is very sluggish, bordering on unusable. What does this job do? Can I shut it off?
Eclipse Helios 会定期开始运行显示“计算附加信息”的作业。在此期间，Eclipse 非常缓慢，几乎无法使用。这个工作是做什么的？我可以关掉它吗？
I just hope that someone in the JDT team comes to sense and gets rid of it, make it go faster, or at the very least change it to something meaningful.
我只是希望 JDT 团队中的某个人能够理解并摆脱它，让它变得更快，或者至少将其更改为有意义的东西。

Other than that:
除此之外：
Disable the virus scanner for Eclipse files (projects and the folder where Eclipse is installed). On demand scanning can cause severe performance problems with Java's lazy loading.
Disable all plugins that you don't need.
Give Eclipse more RAM (512MB or more)
Put 4GB of RAM into your computer. Costs nothing (
禁用 Eclipse 文件（项目和安装 Eclipse 的文件夹）的病毒扫描程序。按需扫描可能会导致 Java 延迟加载的严重性能问题。
禁用所有不需要的插件。
为 Eclipse 提供更多 RAM（512MB 或更多）
将 4GB 的 RAM 放入您的计算机。不花钱（

It's computing/caching some information that will make some operations (like auto suggestion) faster.
它正在计算/缓存一些信息，这将使某些操作（如自动建议）更快。
I can only suggest several things:
我只能建议几点：
- if you installed Mylyn, try to disable the Task-Focused Content Assist
- check the -Xms and -Xmx parameter in eclipse.ini
- try to stop the auto build
- 如果您安装了 Mylyn，请尝试禁用 Task-Focused Content Assist
- 检查 eclipse.ini 中的 -Xms 和 -Xmx 参数
- 尝试停止自动构建
