PERFORMANCE METRICS for RS/6000 SYSTEMS

Section One covers SPEC and LINPACK results for most RS/6000 models and is
relative to performance of a single processor for each system.
         Notebooks                Workstations                 Servers                   SP Nodes

Section Two contains the Commercial (multiuser) performance metrics for
most RS/6000 Server systems; in the case of Symmetric Multi-Processor (SMP)
systems, performance metrics are shown for the various processor
configurations.
          Servers                   SP Nodes

All performance measurements were made with systems running the AIX
operating system. Systems are typically tested with the most recent version
of AIX which was available at the time the test was performed. Practically
all systems shown in these tables were tested with some release of AIX
Version 4.

TPM estimates may be used for comparison and positioning with other
systems. However care must be taken in how they are referenced in any
documents, presentations or other materials. References and associations
with the Transaction Processing Performance Council (TPC) are prohibited by
TPC. The notation, tpm, must always be used with these estimates. An
alternative comparison of performance in a commercial environment is now
being used by IBM and is indicated as Relative OLTP (On-Line Transaction
Processing) Performance. The performance is compared to that of a model
25S/250 performance for this workload.

Note that these performance measurements were all made with systems running
the AIX operating system. Performance measurements are not yet available
for systems running the Solaris or Windows NT operating systems.

NOTES ON PERFORMANCE VALUES

The performance benchmarks and the values shown here were derived using
particular, well configured, development-level computer systems. Unless
otherwise indicated for a system, the values were derived using 32-bit
applications and external cache if external cache is supported on the
system. All performance benchmark values are provided "As Is" and no
warranties or guarantees are stated or implied by IBM.  Actual system
performance may vary and is dependent upon many factors including system
hardware configuration and software design and configuration. Buyers should
consult other sources of information to evaluate the performance of systems
they are considering buying and should consider conducting
application-oriented testing.  For additional information about the
performance benchmarks, values, and systems tested, please contact your
local IBM Branch Office or IBM Authorized Reseller.

Unless otherwise indicated for a system, the performance benchmarks were
conducted using AIX V4.2 or V4.3. IBM C for AIX V3.6.4.0 and XL Fortran
V6.1.0.0 and V7.1.0.0 were the compilers used in the benchmark tests. The
preprocessors used in the benchmark tests include KAP 3.2 for Fortran and
KAP/C 1.4.2 from Kuck & Associates and VAST-2 V4.01X8 from Pacific-Sierra
Research.  The preprocessors were purchased separately from these vendors.

SPECint95: SPEC component-level benchmark that measures integer
performance. Result is the geometric mean of eight tests that comprise the
CINT95 benchmark suite. All of these are written in C language.

SPECint_base95 is the result of the same tests in CINT95 with a maximum of
four compiler flags that must be used in all eight tests. (Units are
relative to SPARCstation 10, which has value of 1.0.)

SPECint_rate95: Geometric average of the eight SPEC rates from the SPEC
integer tests (CINT95).

SPECint_base_rate95 is result of the same tests as CINT95 with a maximum of
four compiler flags that must be used in all eight tests.

SPECfp95: New SPEC component-level benchmark that measures floating point
performance. Result is the geometric mean of ten tests, all written in
FORTRAN, that are included in the CFP95 benchmark suite. SPECfp_base95 is
the result of the same test in CFP95 with a maximum of four compiler flags
that must be used in all ten tests.(Units are relative to SPARCstation 10,
which has value of 1.0.)

SPECfp_rate95: Geometric average of the ten SPEC rates from SPEC
floating-point tests (CFP95).

SPECfp_base_rate95 is the result of the same tests as CFP95 with a maximum
of four compiler flags that must be used in all ten tests.

LINPACK DP: Double precision, n=100 results with AIX XL FORTRAN compiler,
with optimization. Units are megaflops (MFLOPS).

LINPACK SP: Single Precision, n=100 results with AIX XL FORTRAN compiler,
with optimization. Units are megaflops (MFLOPS).

LINPACK TPP: Toward Peak Performance (TPP), n=1,000 results with AIX XL
FORTRAN compiler, with optimization. Units are megaflops (MFLOPS).

SPECweb96 is the maximum number of HTTP operations per second achieved on
the SPECweb96 benchmark without significant degradation of response time.
The web server software is IBM HTTP Server 1.3.4 or Zeus V1.1 from Zeus
Technology Ltd.

Rel. OLTP Perf - Relative OLTP performance is an estimate of commercial
throughput using an IBM analytical model. This model simulates some of the
system's operations of the CPU, caches, and memory in an OLTP environment
but does not simulate the disk or network I/O operations. Although general
database and operating systems parameters are used, the model does not
represent specific databases or AIX versions. With these limitations, ROP
may be used to compare RS/6000 performance. The model 250 is the reference
system and has a value of 1.0.

The following Transaction Processing Council (TPC) benchmarks reflect the
performance of the microprocessor, memory subsystem, disk subsystem, and
some portions of the network:

"tpmC" - TPC Benchmark C throughput measured as the average number of
transactions processed per minute during a valid TPC-C configuration run of
at least twenty minutes.

$/tpmC is TPC Benchmark C price-performance ratio where the estimated
5-year total cost of ownership for system hardware, software, and
maintenance is divided by the throughput, tpmC. For complete disclosure
information please see TPC Web page at http://www.tpc.org.

Notes on Performance Estimates:

Relative OLTP (ROLTP) is an estimate of commercial performance derived from
an IBM analytical model. The model simulates some of the system's
operations such as CPU, cache, and memory. However, the model does not
simulate disk or network I/O operations. Although the model uses general
database and operating system parameters, the model does not reflect
specific databases or AIX versions or releases. Unless otherwise indicated
for a system, the model assumes the use of 32-bit applications. Unless
otherwise indicated for a system, ROLTP is estimated only at the time the
system is introduced. An IBM RS/6000 Model 250 is the baseline reference
system and has a value of 1.0. Although ROLTP may be used to compare
estimated RS/6000 commercial processing performance, actual system
performance may vary and is dependent upon many factors including system
hardware configuration and software design and configuration. All
performance benchmark values are provided "AS IS" and no warranties or
guarantees are stated or implied by IBM. Buyers should consult other
sources of information to evaluate the performance of systems they are
considering buying.
