Eclipse Content Assist Slowness with large projects

Question

I am facing extreme slowness in Java Content Assist with a large java project in Eclipse. The project has a lot of dependent jars (>100). I'm not really sure if the slowness is due to the dependent jars, but I'm guessing thats the case.

Have any of you faced similar issues? I changed the Activation Delay to 500ms to reduce the pain but I still get the "Problems with Content Assist" pop up that suggest disabling Mylyn. I also set the following timeout flag.

-Dorg.eclipse.jdt.ui.codeAssistTimeout=60000

It does not seem to have helped.

-Xmx is set to 900m. I am using a dual core 3 GHz Windows XP 32-bit box with 4 GB RAM.

I would welcome any suggestions or solutions you may have.

Thanks.

Answer 1

If any of those jars or the content in the project are not on a fast, local disk, put them on a fast, local disk.
