Does that mean great or awful?
- svennek 7y agoGreat... order of magnitude-ish higher than a really high end x86 box with pure flash storage...
- GhettoMaestro 7y agoI assume he means that DB perf on mainframes are insane. That would make sense, given their low-latency architecture and I/O throughput capabilities. I would love to see an article that breaks down clustering v. supercomputers v. mainframes in tangible use-cases. It is all a bit opaque to me where one officially starts and the other one(s) begin. As well as where (and to what degree) the value prop is of one versus the others. I've heard folks say mainframes are just legacy stuff carried forward - I've heard others say they have specific use-cases that are not well solved by other current technologies (usually a cost of refactoring). That said, are there any current use-cases, where if I were to write code from ground zero, that are best solved on mainframe, hands down? That is my root question.
