This thread still begs the issue of benchmarking a representative business application across multilple platforms. What application architecture runs across all platforms (z/series, intel, pseries) and operating systems (z/OS, Linux, Unix)? I'd like to suggest SAS. A SAS application that is both cpu and IO intensive would make an interesting benchmark, testing both the strengths and weaknesses of the various platforms and operating systems. <snip> This has been my point. But the common applications use data bases or are accounting applications, or are payroll (a different type of accounting). So a pseudo accounting system report -- say statements that need to know what it was that was ordered, what has been paid, what hasn't, how much is owed, etc. would be a good benchmark tool. And if it were written in COBOL, given that there are COBOL compilers for these platforms, it would give a good throughput demonstration and benchmark. This would drive I/O just like a business application in the real world, could give a definition as to what a transaction is, etc. Regards, Steve Thompson ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
