The documents full-text fields are 140 chars length (tweets). Actually I had looked at those parameters and thought no change was neccessary because the terms per document would be few and the unique term count was nearly 1 M. I don't know exactly but average term count per document text can be 10 in my case.
I think I still do not get why facet.method=enum is faster.
