the job to exit. The same format as rate is used for read vs
write separation.
-rate_poisson=bool Real world random request flow follows Poisson process
- (https://en.wikipedia.org/wiki/Poisson_process). With
- rate_poisson=1, fio tries to simulate request flow under Poisson
- process (instead of even distribution, which is the default).
- Default: false.
+rate_process=str This option controls how fio manages rated IO
+ submissions. The default is 'linear', which submits IO in a
+ linear fashion with fixed delays between IOs that gets
+ adjusted based on IO completion rates. If this is set to
+ 'poisson', fio will submit IO based on a more real world
+ random request flow, known as the Poisson process
+ (https://en.wikipedia.org/wiki/Poisson_process). The lambda
+ will be 10^6 / IOPS for the given workload.
latency_target=int If set, fio will attempt to find the max performance
point that the given workload will run at while maintaining a
to wait for each job to finish, sometimes that is not the
desired action.
+exitall_on_error When one job finishes in error, terminate the rest. The
+ default is to wait for each job to finish.

bwavgtime=int Average the calculated bandwidth over the given time. Value
is specified in milliseconds.
in the specified log file. This feature depends on the
availability of zlib.
-log_store_compressed=bool If set, and log_compression is also set,
- fio will store the log files in a compressed format. They
- can be decompressed with fio, using the --inflate-log
- command line parameter. The files will be stored with a
- .fz suffix.
+log_compression_cpus=str Define the set of CPUs that are allowed to
+ handle online log compression for the IO jobs. This can
+ provide better isolation between performance sensitive jobs,
+ and background compression work.

+log_store_compressed=bool If set, fio will store the log files in a

block_error_percentiles=bool If set, record errors in trim block-sized
units from writes and trims and output a histogram of
