Benchmarks for Linux Applications on S/390 Zseries?

Posted by Cliff on from the lies-statistics-and-benchmarks dept.

qaseem asks: "I am looking for benchmark results of various applications (DB, WebAS, mail, etc.) on Linux on the S/390 mainframe. I am also looking for tools to stress test these applications when installed in the S/390 Linux partition. I was wondering if anyone has seen such information or tried such tools. On a side note I am also interested in finding a way to relate the MIPS speed of the S/390 to the world of MHz or GHz on other platforms."

    You won't learn too much when you compare MHz to MIPS with an S/390. They are fairly slow, but they do have a TON of memory bandwidth and very fast RAM. At my school we still do mainframe asm programming, and it was pretty clear that machine could move memory like crazy.

    DB apps and the like should run nice and fast... makes sense... that is the reason S/390's still exist.

      They also have I/O channel controllers, which are like simple processors dedicated to I/O related tasks that can run user-specified programs. This takes some of the load off the main processor. The main processor doesn't have to do the bit fiddling needed in PC device drivers.
