Re: Native sFTP?

From: Richard Schoen
Since you wrote the redbook on Java for the iSeries, could you
tell me how to speed it up to the levels that it runs on Windows?

Is that really true? Or is it just a false perception carried over from the days when shops tried to run Java on older, constrained AS/400 models?

Or could it be a false perception resulting from running complex workloads under IBM i vs. simple workloads under Windows? I still see that in most environments today, where IBM i is running complex interactive and batch workloads, while Wintel servers are pretty much dedicated to a single task - application serving or database serving.

My perception is that given a comparable CPU & memory configuration, and workload configurations, Java performance is about the same under both platforms.

Like Simon, it puzzles and concerns me to continue seeing workloads moving away from the IBM i native virtual machine. I'd personally like to see IBM and other vendors investing more in the native environment. A native sFTP would be a good candidate for IBM to bundle with IBM i. It would be hard for any other vendor to generate a separate revenue stream from it.

I developed quite a bit of plumbing and infrastructure for native IBM i Web applications, but there are a lot of barriers to marketing that type of product, so I've since moved on to developing business applications. Still I'm glad that I invested in native IBM i plumbing and framework code, because it provides a great basis for business applications.
