Tradeoffs such as "if an I/O error occurs, the program immediately segfaults." Also, I doubt you're I/O bound to the point where mmap noticeably better than read, but I guess it's fine for an experiment.
- jibal 10mo agoAn I/O error on a mmapped file causes a SIGBUS, which the program can catch and report. And I/O bound programs are I/O bound whereas programs that aren't, aren't, so it really isn't meaningful to talk about whether "you" are I/O bound to the point that it's significant--maybe you are, maybe you aren't. I agree about experimentation.
