Hello,

The reason why auto-completion with auto-complete-mode is slow might be because of
flyspell-mode. Do you use it by default on org-mode by any chance?

I tried disabling flyspell-mode and got good results.(Not as fast as pabbrev-mode but fast enough)

I also posted an issue here
https://github.com/auto-complete/auto-complete/issues/435

the M-x profile-start, M-x profile-report was really helpful here.

Best regards,

Jeremie

I used to use auto-complete but gave up for just this
reason.  Interestingly, in my initialisation file, I have the following
comment:

    ;; latest version 1.3.1 is too slow; back to 0.2.0

In any case, I use pabbrev instead which may suit you.

However, if you find a solution to the speed problems with
auto-complete, do let us know!
