==Description==

This parameter affects processing of finds for <var>Imagine Transparency</var> requests.

When a <var>Find</var> request is sent to a <var>Transparency</var> broker, the broker will respond with a list zero or more records thaty satisfy the criteria. To process those records, a separate request might need to be sent to the broker to retrieve each record. But, usually, a <var>Find</var> is immediately followed by a <var>For</var> loop on the matching records, so it can be useful for the broker to "prefetch" some number of records that satisfy the <var>Find</var> criteria, reducing the latency and CPU overhead of processing the extra record retrieval request. The default value of 1 should be fine for most applications though, if many finds in an application match many records, and all records are usually scanned, one might improve performance with a larger <var>IMGPREF</var>. The main downside of a large <var>IMGPREF</var> might be that records that are never scanned (because of early exit from <var>For</var> loops) might be sent from the broker to <var>Model 204</var>.
