Miklos,
What do you mean by 'zlib'? Is it free on z/OS?

Hi
A few years ago I have tried with hardware compression, as we are using
intensively the "zlib" library (http://www.ietf.org/rfc/rfc1950.txt) to
compress/expand .
Never got a proper answer, and till now not clear, in which case would
bring the hardware compression some CPU reduction

Ron, is it generally the case that CPU is saved on read? I'm seeing QSAM
with HDC jobsteps showing very high CPU. But then they seem to both write
and read. Enough CPU to potentially suffer from queuing.
(And, yes, I know you were talking about a different category of HDC
usage.)
