I was wondering how many lines of code it was possible to read per hour. I found on the Wikipedia code review article the claim: “Code review rates should be between 200 and 400 lines of code per hour.” They say any faster is too fast to find errors. I also found on the Wikipedia article source lines of code that a contemporary Linux kernel has 20 million lines-of-code. So if you didn’t sleep and read code 24×7 you could read the Linux kernel in a little over 5 years…
