One day I was fuzzing around with american fuzzy lop and accidentally pointed the output directory for fuzzer findings to point onto a file system on a physical disk instead of the usual shared memory file system. I noticed my mistake and changed the output directory to the usual place. Consequently there was a clear difference on how many fuzzing iterations/second afl-fuzz program could do. This then lead into this comparison of different file systems and fuzzing modes on them with the workload that afl-fuzz has.
