Eclipse auto suggest list very slow

Question

By auto suggest, I mean that intellisense that pops up when I write something. My problem is that if I write something like btnMyButton. after typing . I get to wait a few seconds until eclipse populates the list with events for button. I am using Eclipse to develop Android applications.

Can this be sped up? I have a Quad Core processor and 4 GB of ram. The rest of Eclipse is working fine.

Yeah, I've seen this same problem - Eclipse with Android, the code-completion popups take forever. Dunno why yet. — Ladlestein, Oct 21 '10 at 00:13
Interestingly, I have this issue with a C++ project, but not my Java projects. — kevinarpe, Jun 13 '11 at 12:03

I was also experiencing this problem. I found my answer here:

https://groups.google.com/group/android-developers/browse_thread/thread/85dc1aae3bafff5e

In summary:

turn off JAX-WS Proposals in Content Assist

Window > Preferences --> Java > Editor > Content Assist > Advanced

I don't have "JAX-WS Proposals" in that list. I have unchecked everything other than "Java Proposals" and Eclipse is still very slow. – Jonas May 19 '11 at 17:20

You can also try changing the Auto Activation parameters. You can either disable it completely or you can increase the "delay" to make sure it does not hang your Editor while you are typing. – Sameer Aug 03 '12 at 05:19
Same Problem, but no "JAX-WS" present, disabling "SWT Template Proposal" and "Chain Template Proposal" resulted in a huge speedup. (On top some of the exceptions thrown sometimes did disappear from the log...) – msebas Aug 26 '19 at 10:33
The problem went away for me after disabling Java Proposals (Code Recommenders) and enabling Java Proposals instead (without the Code Recommenders tag) – Vincentius Kevin Sep 16 '19 at 10:32

When I changed delay to 1 (ms) it solved autocompletion problem in Eclipse for C++.it is now very fast:

I unchecked "Fill method arguments and show guessed arguments" under Window > Preferences --> Java > Editor > Content Assist

This improved the content assist speed in my Eclipse

Uncheck all, other than API Tools Proposals and Java Proposals in Window > Preferences --> Java > Editor > Content Assist.

Refer to the below screenshot.

you can add disable auto activation in Window > Preferences --> Java > Editor > Content Assist

This way you can activate it when you need it by Ctrl + Space

It is slow in the case of controls, like buttons, imageviews etc. If I have a class and i type Classname.getSOmeMember() the menu is very fast. – Alin Oct 21 '10 at 05:50
I see Eclipse being slower in Windows 7 and faster on Windows XP – Alin Oct 29 '10 at 15:49
