The minyanim where I daven:
1. Weekday shacharit: nusach Sfard, from Rabbe Yishmael to the end: 30 – 33 minutes, depending on who’s davening for the amud.
2. Weekday arvit: 8 – 10 minutes, an extra three minutes if the Rav is there.
3. Shabbat morning: nusach Sfard, from brachot to the end (includes Anim Zmerot) – about 90 minutes, give or take a few, depending on the length of the parsha and the baal koreh.
I go back to America and I can’t handle the 2.5 – 3 hour Shabbat morning davening anymore. I sit and squirm, unless I get to a nice hashkama minyan.
