Re: 20 years ago

This list is about RPG, on IBM i.

Some things, like big sub files, can have a better performance in web than
in green screen.

When the web returns results in miliseconds, the green screen does not
appear faster.

Since the web is "connectionless" the programs are not the same as for
green screen. But the performance of a good web application beats any
user, even using the bar code scanner.

Sory, English is not my mother language,

I think a lot of misunderstandings can be explained by that.

In you do your web using php in a cheap Linux server, comunicating with

the IBM i, the result will be worst than green screen. Besides, cheap Linux
servers do not scale well. You need Linux mainframes.

IBM i wasn't in the mix.

I expect Green Screen performance to be always ahead of Web when using
similar underlying techniques.

I can see your opinions are based in experince with others platforms,

that you extrapolate to the IBM, not valid.

From my limited experience I assert, some facts are similar enough for
extrapolation. See below.

With Apache, RPG, SQL, my P9, having only one core activated, can

prossess over a hundred transactions every second at peack time. I think
scale will not be a problem.

I'd expect DB2 on IBM i to indeed behave better than MySQL on some Linux.
Within the limits some very fundamental technological challenges, such as
locking. Down below, everybody eventually cooks with water.

:wq! PoC
