I did some benchmarks a long time ago on linux on zSeries. It is against the agreements to publish such benchmarks. But it got me thinking what they have done well Amazing: - Longevity - you can run code from 30-40 years ago easily. The only real operating system at this point to do this. Maybe linux will be able to say this in 1-2 decades. Pretty good: - I/O is pretty good - Security - all the datasets were encrypted Not great: - Costs - Open standards
