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 SourceForge.net 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.
IOMeter testing shows the Colossus favors larger block sizes and combined reads and writes, such as the File Server, Database, and Workstation profiles. The advantage seen by other Indilinx units in the Web Server testing is not shared by the Colossus due to its lack of AHCI / NCQ support. This is evident across all tests, as the Colossus remains perfectly flat across the board.
The significantly faster writes of the Colossus enable it to push past the X25-M G1 in Database and Workstation tests, but as soon as queue depth climbs past 1 it is once again overtaken by the aging Intel SSD. Despite having less than half the write speed, the X25-M G2 continues to dominate this particular group of tests.
