That's quite a mouthful, Kebabbert. I'm going to try to address the silliness here bit by bit.
"Awkward it is, that we read about the TurboHercules Mainframe emulator that gives 3.200 MIPS on an 8-way x86 server - that is quite decent performance for a fraction of the price."
Wow! Roughly 6% of the CPU performance of a mainframe, a system designed for moderate CPU performance and high I/O! Truly impressive!
"TurboHercules says their customers are interested, because when their Mainframe crashes, they can switch to an cheap x86 server."
I've spent a fair amount of time with TurboHerc marketing materials, and they don't claim this. They say that a commodity system can be a warm standby failover system. Nobody, even NonStop or Stratus customers, puts all of their eggs in one basket when they can avoid it.
"And the "worlds fastest cpu", z196, is in fact slower than an Intel Nehalem-EX. You need several z196 to match one Intel Nehalem-EX in terms of cpu power."
Floating-point, maybe. Integer, not close. I/O bandwidth, orders of magnitude of difference.
"And about the "slow" SPARC cpus, sure they are slow, says IBM. Let me see, who has the world record in TPC-C? 30 million? Who has several other performance world records, beating the POWER7? It is funny that a 1.6GHz cpu can be fastest in the world on several benchmarks, even faster than the "mighty" POWER7."
TPC-C is a meaningless benchmark, and has been for years. Sun wisely abstained from it, recognizing that it was basically silly. Additionally, I've been hearing some really interesting things about the supposedly invincible T3, although I haven't used one myself...
-Oracle reps taking months to provide a price quote, resulting in customers having to compare Oracle list price to HP/IBM discounted price
-Performance on throughput-oriented multithread workloads being vastly slower than a cheaper AMD Magny-Cours
-Failure by Oracle to provide credible roadmaps for >4socket machines
Anyway, if you insist on using TPC, the fastest non-clustered result is a Power6 machine, followed by a Superdome. If you do some math, it can be assumed that a single Power 795 would be well into the 15mnTPC territory. How many boxes did it take Oracle to get to 30mn again? And how many licenses are they selling, for that number of cores?
