Has anyone done any benchmarking on FOCUS and RDB V3.0? For example, does FOCUS slow down the data access rate when using RDB? How about RALY and TEAMDATA vs. FOCUS? If no one has done any benchmarks, does anyone have any suggestions on how to do them? Steve

| 178.1 | focus benchmark | MEMV01::COPPERSMITH | SYSTEM-W-RELFLT, reality fault | Mon Feb 06 1989 16:10 | 21 |
We benchmarked a FOCUS application using DTM, a Fortran benchmarking
subroutine from the VTX Toolshed (modified for use in Fuselib) and
SPM. DTM was required for automated scripting because the FOCUS
application was driven by FMS screens.
This approach pushed the uncertainty principle a little bit, because
we were using software on a system to measure the effect of other
software on the system, but since the goal was to derive minimum
system configurations for the application, this extra load actually
served to provide the estimate with a margin of safety.
The benchmark also progressed at machine speed rather than human
speed (of input), but the benefit of the automation was that the
benchmark was reproducible across different systems.
The experimental design and results are available from MEM Finance
IS. The system measured was the SMIRS system.

| 178.2 | improvements to RDB interface | FDCV10::REVRPT | Mon Apr 03 1989 15:52 | 16 | |
Our group is using FOCUS to go against an Rdb database and encountered
some performance problems and decided to explore. We used a simple
fex to navigate the entire relation sequentially and sum a $ field.
The target relation has about 640,000 entries. We also built a FOCUS
database containing identical data. A simple RDO request took 3
mins. of CPU to sum the field. FOCUS with a FOCUS db took 4 mins.
of CPU time to produce the total. FOUS with Rdb took 19 mins CPU.
The FOCUS hotline told me that the technical group is currently
working on the FOCUS/Rdb interface and should have a new beta version
(5.22 ?) available in 2 weeks. The current interface instructs Rdb
to returns each field to FOCUS where the sum takes place. The next
release will allow Rdb to produce the sum and pass the one field
back to FOCUS.
