Something like this used[1] to work :

   from cubicweb.web import uicfg, formwidgets as fw

   _affk = uicfg.autoform_field_kwargs
   _affk.tag_subject_of(('Expense', 'spent_for', '*'),
                        {'widget': fw.LazyRestrictedAutoCompletionWidget(
               autocomplete_settings={'limit': 100,
                                      'delay': 300}),

Notice the 'delay' settings.

[1] I say "used" because we've switched to jquery.ui.autocomplete widget 
a few months ago and it might not work as well as before.
