Generally I read 200-400 pages a day. I am semi retired (work 6 months a year) so I have more time for reading than most. I generally read at the rate of 800 words a minute.
A bit anal of me to know this, and up to about a week ago I didn't. Saw a post on MR that stated that 45 pages per minute was considered fast in Holland. Was curious so looked up average reading times etc. Got more curious and put little kitchen timer beside my bed

Looked up page numbers in stores to see how they coincided to page numbers in my reader.
Then I saw article(s) about Harry Bloom who read 10,000 words per hour in his prime, and has been reduced to 5,000 word per hour now that he has aged. With close to perfect retention. That is humbling.
The timer is back on it's shelf over the stove.
