+ since the speed may be different. It is possible to specify
+ a number of IO's to do before getting a new offset - this
+ is only useful for random IO, where fio would normally
+ generate a new random offset for every IO. If you append
+ eg 8 to randread, you would get a new random offset for
+ every 8 IO's. The result would be a seek for only every 8
+ IO's, instead of for every IO. Use rw=randread:8 to specify
+ that.
+
+randrepeat=bool For random IO workloads, seed the generator in a predictable
+ way so that results are repeatable across repetitions.
+
+fadvise_hint=bool By default, fio will use fadvise() to advise the kernel
+ on what IO patterns it is likely to issue. Sometimes you
+ want to test specific IO patterns without telling the
+ kernel about it, in which case you can disable this option.
+ If set, fio will use POSIX_FADV_SEQUENTIAL for sequential
+ IO and POSIX_FADV_RANDOM for random IO.
