So, I benchmarked before and after this patch to icomplete.el:
diff --git a/lisp/icomplete.el b/lisp/icomplete.el

The patch itself nullifies the calculation of the 'determ' thing that I
and presumably some other users don't value that much. It doesn't
affect fido-mode's basic funcionality.
How did I benchmark? Well, to measure the delay the user experiences
until all completions are presented I had to take out the
`while-no-input` in icomplete-exhibit so that this test would work:
;; After the form, type C-u C-x C-e C-m in quick succession
(benchmark-run (completing-read "bla" obarray))
If I don't remove this `while-no-input`, icomplete will not lose time
showing all the completions and will instead select just the first one.
That's a very nice feature for actual use, but for this benchmark that
is not what I want: I want to measure the time to show all the
completions.
Then, the times presented by benchmark-run are the same that the user
sees if he waits to see the completions. Now the values:
