The provider of the standard libraries so that the method linked in is
the MI accessing method.

But again that is a complaint about the compiler. There is no
requirement that there be some inefficient string processing. Nor is
there a requirement that only RPG get to use MIs when they suit a purpose.

My contention is that it is not a requirement of "modern programming
languages" that they be able to burn extra processing cycles. That is a
requirement of less than optimum compilers and poorly coded standard
libraries.

So beating this problem isn't a matter of plugging in a faster processor
to overcome the poor tools, that just happens to be the solution in the
PC world. Yours is the first time I've heard that described as a
"benefit." I've always heard that complained about, the way bloated
software on PCs requires faster and faster processors to keep it alive.

That said, I have no argument against plugging in faster and faster
processors in the iSeries. I don't know what the hold up is and I'd like
to see GHz speeds, but not as a way of allowing poorly written or
bloated code to be ported to the platform nor as a replacement for
considering the workload being handled.
