From Cobol, to the IBM mainframe, to C, to x86, these high-tech senior citizens not only keep kicking but provide the foundations for many vital systems that keep IT humming.

Mainframe have never been marketed for CPU-intensive tasks. They're highly reliable machines designed to handle large-I/O applications, which is why you seem them used for airline reservation systems and other similar things which require low latency and a large number of concurrent users.

So we agree then that Mainframe cpus have weak cpus? That Intels latest high end server cpus are much faster?

Of course I also agree on the rest of what you say. I have never denied that Mainframes have superior I/O. You can not find any posts from me, saying something else. Because I know Mainframes have good I/O. I have never disputed that. 296.000 I/O channels and lot of I/O cpus help a lot.
