每次击键后，Eclipse都会不断重建准确的宇宙模型

Question

I've tried so much I'm almost breaking my laptop on my forehead. But it was an expensive piece of equipment and I need it for my job, so I will try StackOverflow first.

I've got this huge Node.JS project in Eclipse . Eclipse has always been sluggish, but now it's gotten to the point where after every few keystrokes, Eclipse will freeze for minutes with the processor at 100%, often ending with some random useless error message like garbage collection ran out of memory or whatever.

Whatever it is, I don't need it to happen after every few keystrokes! Sometimes, this error message appears, with the advise to disable Template Proposals. I've had the same dialog advising me to disable pretty much everything else that is useful, to the point that Eclipse is starting to become quite similar to your next enhanced Notepad application.

• Is it really so impossible to have IDE-trickery such as code assist and completion (AKA the whole reason to use an IDE in the first place) with Eclipse, even working with projects bigger than two lines of code?
• Why would Ctrl+Space take a minute of 100% CPU when the only assist I have enabled is a handful of templates and the others are disabled?

Please share the secret option with me that makes Eclipse usable.

1. Preferences --> Editors --> Content Assist : disable auto activation. You can still use it with Ctrl + <Space> .

2. Disable build on save for the workspace.

3. As a last resort disable Preferences --> Validation

4. You can Increase the memory available to eclipse by providing the -Xms and -Xmx parameters at startup for eg : eclipse -vmargs -Xms256M -Xmx1024M . More info at the eclipse wiki .
