If you are talking a lot of math, particularly floating point math, then
Intel is going to be king with its higher MHz.
If you are talking lots of I/O with a fancy external storage plus
stripping, then z-Series is going to eat Intel's lunch.

Please respond to
Linux on 390 Port
I would guess that the SQL is not very optimized. Also, the app pushes a
lot of math that could be done client side to the database.
700 may be a somewhat low, but the HPUX server had two 440mhz PA-RISC 8?00
cpu's. When we moved it, it ate all of one IFL, plus a bit. It's bloated
since then and has been chewing on a good portion of both recently.

700Mhz? That seems pretty low.
