Performance in Intel IOMeter FileServer and WebServer Patterns
Let’s see how fast our external hard drive will be when working with server patterns:
When the hard disk drive works under FileServer workload, FireWire interface becomes more attractive than USB 2.0. In case of 1 and 4 outgoing requests the advantage is stable, though not that huge. However, as the number of outgoing requests grows up, the performance gap also increases and by the time we reach 256 requests, the HDD performance more than doubles. The two IEEE 1394 controllers run equally efficient in this case.
When this hard disk drive is used as a part of a Web-server, the picture is generally the same. Under linear workload the interface type doesn’t matter for the drive, however, as the number of processed requests reaches 4 already, FireWire controllers speed up the processing. Just like in the previous pattern, we cannot name any of the two IEEE 1394 controllers the winner.
