In contrast, the same query run a second time with IWA finished in less than a minute.

相反，结合 IWA 技术再此运行相同查询时，不到 1 分钟即可完成此项查询。

Running this query with IWA took nine minutes, and we were able to reduce the size of the Informix memory buffers.

在结合 IWA 技术的情况下运行此项查询只需花费 9 分钟时间，我们可以减少 Informix 内存缓冲。

When an application sends a query to Informix, the Informix optimizer decides whether the query should be sent to IWA.
