Well, as an old DEC guy who later worked for IBM... I
agree, although
So, there are at least tree of us holding the
banner for the real (big) guys :)
with Posix Compliant mainframe software that meets the
Unix spec
and runs the Apache webserver... mainframes aren't mainframes anymore.
Oh-Oh, did you ever took a look at the resulting ASSM code ?
Did yo uever trace the extreamly inperformant I/O calls for
unix like file systems ?
A mainframe can only produce it's marvelous throughput if
the data is well prepared - handling every byte of a string
inside a loop and check for zero is like using a using a
truck for moving a pice of paper.
