I've had a few discussions with various co-congregants about "fast" and "slow" minyanim.
Our shul building has 2 minyanim. The main one has a professional chazzan. We begin Shabbat services at 9 am and are done between 11:30 and noon which includes approx. a 15 minute Rabbi's sermon. Most shuls in my neighborhood start at 9a and finish by 11:30, so it seems that 2.5 hours is the common service length.
In the adjoining building to our shul, they begin at 9 and are done about 10:30 including the rabbi's sermon.
People in my shul say "the other minyan davens too fast." Some others who attend other shuls in my neighborhood who end at 11:30 say that if we end at noon, we are davening too slowly.
My argument is that the speed doesn't matter, and there is no such thing as "fast" or slow" providing that the chazzan and Torah readers pronounce each word clearly and don't omit, slur or "swallow" the words. It is possible to say a "fast" Amidah yet pronounce each word quickly.
I think that I am correct in my thinking, but I'm wondering if there are any halachot or Rabbinical teshuvot that have a suggested amount of time that certain sections of the davening should take?
