Two anecdotes:
My rav told me that when he was learning in BMG the oilam used to learn 35 blatt first seder and 35 blatt second seder each zman and R’ Aharon used to get upset at them for going so slow…
I heard R’ Yosef Tendler (Ner Israel) say over that he was once shmoozing with R’ Shneur (they were both kollel yungerleit at the time) and R’ Shneur told him that he once asked his grandfather, R’ Isser Zalman, what is the proper way to learn? R’ Isser Zalman told him, “one blatt a week be’iyun, and seven blatt a day bekius…”
Chacham-
I don’t know how old you are, but in NIRC there are shiurim that go much faster than the average American yeshiva. For example, I was in R’ Tvi Berkowitz’s shiur for BK and we got up to daf chaf alef or so (other yeshivas are lucky to get past daf vav) first seder.
