| Popis: | The perceived I/O performance of a shared file system heavily depends on the usage pattern expressed by all concurrent jobs. From the perspective of a single user or job, the achieved I/O throughput can vary significantly due to activities conducted by other users or system services like RAID rebuilds. As these activities are hidden, users wonder about the cause of observed slowdown and may contact the service desk to report an unusual slow system. |
