auto-complete: dropdown display delay

[Miguel Guedes]

Hello List,


Does anyone know how to decrease the time it takes for auto-complete [0] 
to display the dropdown menu in *every* instance? 

I've noticed the delay I've specified in `ac-delay' and `ac-auto-show-
menu' is enforced *only* in those instances that require a trigger 
character/string (e.g. `:' or `->'). However those instances that require 
2 characters to be typed, the dropdown takes >3 seconds to be shown. 
Doing `M-x auto-complete' results in the popup being shown immediately so 
it's not like auto-complete is busy processing - the delay is being 
overriden somehow.

Would appreciate some input on this as I find it a terrific programming 
tool.

Here's how I set it up:

(ac-config-default)
(global-auto-complete-mode t)
(setq ac-auto-show-menu    0.2)
(setq ac-delay             0.2)
(setq ac-menu-height       20)
(setq ac-auto-start t)
(setq ac-show-menu-immediately-on-auto-complete t)
