IOMeter v2006.07.27 – IOps

Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation and announced at the Intel Developers Forum (IDF) on February 17, 1998 – since then it got wide spread within the industry.

Meanwhile Intel has discontinued to work on Iometer and it was given to the Open Source Development Lab (OSDL). In November 2001, a project was registered at and an initial drop was provided. Since the relaunch in February 2003, the project is driven by an international group of individuals who are continuesly improving, porting and extend the product.

While Agility 3 was not able to scale as high as the Vertex 3, it actually fared better at lower queue depths, which is the place the kernel sits most of the time when hit with a typical desktop user workload.

It’s worth pointing out that in this same low queu depth region, the Intel 320 Series SSD trounces both of them, and does so even while bottlenecked by its SATA 3Gb/sec interface.
