I do hope Sridhar will take his time to address this. :)
Well, if not I will. While hercules is WAY cool (I've played with it
a bit, along with OS/360 since it's "public domain"), it'll never beat
the real thing. On my shiny new Dual Athlon 1700+ (1.466GHz) (however
I suspect that hercules is only using one processor to decode/execute
instructions), I get a Super-Speedy 5MIPS rating at most. While this
is about 2x as much as my old Athlon 700 system gave, it's nowhere
near as fast as any modern S/390 or zSeries, and probably not even as
fast as the S/390 on a card that IBM use to sell with a PS/2 as a
P/390.
It might be about the same league as a P/390. Certainly not a P/390E, and
nowhere near even the minimum configuration of the oldest S/390.
Peace... Sridhar
