"....Still looking for any part of your comment where you even pretend Rock isn't dead, or try and present some argument as to how Oracle can retain any enterprise customers without a proper enterprise CPU...."

What are you talking about? I answered to this. Do you have a hard time understanding what others write? I wrote: "Regarding SUN dropping Rock, yes I suspect that is true. So what? There IS a high performant SPARC cpu in the Fujitsu Venus CPU. That octocore SPARC will reach 128 GFlops". Ergo, I dont pretend Rock is alive. I also talk about another Enterprise SPARC CPU, than Niagara, which is called Venus.

"....Take a quick look through history and you'll find plenty of old C UNIX apps that ran on a lot less than 32MB of memory, they are all candidates to run in cache on a modern CPU..." I dont understand how you can write such really uneducated things? Did you ever think before writing that? You know, a cache mustnt only hold the server application, it will also try to fit in the OS, kernel, and all the clients data sets. I explained this many a times. And still you dont understand? Look, a cache tries to hold everything recently accessed. Not only a selected pieces from the software. The cache doesnt know if it should fit in the server app into it's cache. Which it should NOT try to do. Why? The problem is localization. A small part of the code will use almost all computations. Hence, of that server application, only a small part of the code will be accessed frequently. It is a DUMB thing to try to fit in the whole server application. Therefore the cache will never try to fit in the whole server app. It will fit in things that accessed frequently, such as parts of the Kernel, server app, client data sets, etc - which can never fit into a cache.

Dont you get it? How many times must I explain? A cache can never fit in a server workload! Read this again, but slooooooowly (like the Power6) and maybe you will understand! Jesus man, you must have had a hard time in school when a teacher tried to explain things to you.

Can you answer me how one Sun T5540 server is twice as fast as three IBM P570 servers on SAP benches? How is that possible if the Niagara cache is too small? Can you give a good explanation, or can you not?
