Is it just some ruby files where you notice this, or all of them?
Does the problem occur with other file types or just ruby?
Are there other plugins mapped to the tab key (:verbose imap )?
If you start vim with the minimal settings does the problem still occur?
$ vim -u NONE -U NONE --cmd "set nocp | sy on | filetype plugin indent on | ru plugin/supertab.vim"
Note: if supertab is in a pathogen or similar directory, then you'll need to add a | rtp+=/path/to/supertab/dir/
before the | ru plugin/supertab.vim
part in the command above.

I followed the route you suggested and found there was no problem with minimal settings, and then I eventually managed to figure out the root of the problem --
let ruby_fold=1
syntax on
If ruby_fold is not enabled things work fine, or if ruby_fold is enabled and syntax highlighting is off things work fine. This explains why the problem occurs sporadically -- in the same file, tab completion is very slow in one place but fast in another.
I suppose the solution for now will have to be to turn ruby_fold off and try to find an alternative.

Thanks for posting an update, it's good to know the cause should other users encounter the same issue.
I'm going to go ahead and close this ticket though since inefficient syntax files are outside the scope of supertab ;).
