Is SPECsfs2008 a CPU-intensive or I/O-intensive benchmark?
SPECsfs2008 is a system-level benchmark that heavily exercises CPU, mass storage and network components. The greatest emphasis is on I/O, especially as it relates to operating and file system software. To obtain the best performance for a system running SPECsfs2008, the vendor will typically add additional hardware — such as memory, disk controllers, disks, network controllers and buffer cache — as needed in order to help alleviate I/O bottlenecks and to ensure that server CPUs are used fully.
