There is some information in the Redbook, and it is _old_. Obviously, they couldn't have used any compiler newer than the late 90s. Hardware: The same OS/390 hardware was used for all the measurement tests presented in this book. This configuration was a four member OS/390 Parallel Sysplex, but only two members of this sysplex were used for the measurement; one to provide a platform for the system under test, and a second to provide a platform for the network simulation driver (when using TPNS). Each sysplex member ran on a single 9672 Central Electronic Complex (CEC). This configuration comprised: • A 9672-R55 processor (2GB storage) with 2 Cryptographic Coprocessors available where noted. • A 9674-C05 coupling facility (2GB storage) • Adequate RAMAC DASD to eliminate I/O constraints For tests needing Web client simulations, either TPNS on OS/390 or the Compuware QALoad product on two nodes of an SP2 AIX processor was used. The network connecting the OS/390 and AIX systems comprised: • An ATM LAN emulation client (Token Ring) adaptor card on each of the AIX SP2 nodes • An ATM (Asynchronous Transfer Mode) network • An OSA-2 card on the S/390 processor set to operate in TCP/IP Passthru Mode to provide token-ring LAN emulation client (LEC) services via the ATM connection. Software: • OS/390 V2.7, including: - VTAMV4.7 - DFSMS V1.5 (VSAM) • CICS Transaction Server for OS/390 V1.3 • TPNS V3.5 • WebSphere Application Server V1.1, including: - IBM HTTP Server V5.1 • OS/390 Java Development Kit V1.1.8 • OS/390 CICS Transaction Gateway V3.1 • Compuware QALoad/QARun software at V4.3 • AIX V4.2.1.0 http://www.redbooks.ibm.com/redbooks/pdfs/sg245748.pdf Their comparison is completely ridiculous. I'm far from a CICS expert, but my guess would be that the CWS related components from the late 90s are _far_ different (and less efficient) than the ones available today. Or even in this decade, for that matter. In addition to all the other issues with this extrapolation. ---------------------------------------------------------------------- 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
