Mainframes are supposed to be good at the type of jobs that you can't really do an apples to apples comparison of - they're not supposed to be running linear algebra benchmarks, however equally a lot of quasi-distributed systems (some cloud infra or whatever) performance will completely collapse when you try to scale them beyond little benchmarks.
I've read IBMs docs on their processor architectures, I'm sure they're fast enough but no more than that.
Wouldn't choose one for infrastructure but would love to have a play with a mainframe.

I’ve played with the LinuxONE community cloud for a while and one thing that quickly become obvious is how ridiculously fast the machines are. Not only the 5+ GHz CPUs but all that very smart IO that seems to magically predict what the CPU will want, and have it on hand. And the cache architecture of the z16 CPU is awesome.
