My minyan:
Brachos till Hoidu? 4 minutes, including korbanot
Hoidu till Borchu? 7 to 8 minutes, depending on who’s davening
Borchu till the start of SE? 4 minutes
SE? I think 5 to 6 minutes, I don’t usually look at the clock when we start
Chazarahs ha’Shatz? quick, but I don’t know off hand; perhaps 5 minutes including duchening
Tachnun till Olainu? short tachanun to the end of ein Kaylokaynu is about 6 minutes, I think; it may be a bit shorter
All in all, a non-laining day with tachunun is about 34-37 minutes, depending on the chazan.
