We had a similar problem with IBM's XML parser, which is huge and was constantly being reFETCHed.
At startup time we went through a list of programs and loaded them and threw away the returned address. These modules are now loaded with a use count of 1. All subsequent LOADs/FETCHes finds them in storage. Because the use count now never goes back to zero these modules will stay in Virtual storage until termination. We dropped many thousands of I/Os per minute. About 10-20 lines of assembler code and a list of the programs required. Hope this helps.
