For those of you who also follow DB2/Z this is effectively the Smart Analytics Optimizer for Informix. The above link is to our documentation on the product.
I've had the opportunity to work with members of my own team in the Accelerated Value Program on the Ultimate Warehouse edition for the last month. It can be made transparent to the application developer and Flat out flies. Once setup and enabled IWA has generated, for my team so far, a performance improvement of more than 66 times the speed of the same informix query when not accelerated. That query had already been significantly improved because of the Star/Snowflake support in the Optimizer added in 11.70.FC1. Essentially IWA has turned the OLAP/ROLAP queries we were running into ROLAP/OLAP queries with OLTP response time.
If you noticed above, possibly the best part of this is that it is transparent to the application, so if you are using IBM Cognos, or any other Business Intelligence type of tool, you just have to request the DBA to turn IWA on for you, you don't have to get any special "IWA aware" tool to use the product.
I will definitely talk more about the IWA as I have time and am allowed. For those of us that have to write against and Use warehouses or Data marts, this is a big deal.
