Is the number of jobs impacting the total runtime of fio benchmark? 1. In general you want to increment numjobs if you want to create a multi-threaded workload. One example would be to drive IOPS, since a single-threaded workload might become CPU-bound instead of IO-bound. 2. This depends on how you set up your workload in your job file. Runtime can be global affecting all jobs or different jobs can have different runtimes.
