Remember how old the 3270 architecture is. Wikipedia says about 1972. Think 1 Mhz 8080 as "top of the line" micro
processor. The original 3277 and its controllers were STUPID. Rather than put a more powerful processor in the controller, IBM
decided to offload the "complicated" function of calculating the position of the data into the host. Made of discrete
transistors and resistors! Very primitive. So, the host just sent a simple to understand "buffer address" (a single
number) to the 3274. It basically just starting stuffing data characters at that location in a RAM buffer. More power == most
cost == fewer purchases. Much like some of the "krud" in z/OS today due to "short sighted" architects who
were worried about memory and slow CPUs and expensive DASD.
The answer to these problems is obvious: Convert from archaic z/OS to modern Windows 8! At least
that's what a lot of "Windows weenies" around here are saying. Over and over and over and
over. "Better! Faster!! Cheaper!!!" is their cry. Anything z/OS can do, they state can be
done using Windows and at lower TCO. Herr Gobbles would be proud of them.

Leave us also keep in mind another set of parameters that are significant.
While the Windoze-based processors may be blindingly fast at doing
arithmetic, when it comes to large-scale data movements they are
abysmally slooooooooow. Large-scale data mining operations are nothing
more than a far-off dream of the future for Windoze processors.
Similarly, processing of large matrices is a similar pipe-dream, unless
the entire matrix can be maintained in RAM, as opposed to disk storage.
"Windoze security" is an oxymoron, as is "reliability" (but it's slowly
improving). We know that the big iron has a few drawbacks; when are the
"Windoze Weenies" going to realize that the same is true of their platforms?
