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.
These results are very interesting: on the first test that emulates a web server we see the OCZ SSD drive has a HUGE lead over the competing cards in terms of I/O operations per second. It is almost an order of magnitude better. In other tests though, the OCZ drive performs very differently and is most often at the bottom of the pack. Why? It is likely because of the workloads that the web server has compared to the other three scenarios: web servers typically serve lots of very small files. That would lend itself well to a drive that has low seek times (like the SSD does) while the file server test (and parts of the database and workstation tests) are using larger pieces of data that depend as much on bandwidth as they do latency and thus the SSD loses its advantage.
