- GENERAL INFORMATION
-
- These system benchmarks are a series of more than two dozen
- tests grouped into six modules. Each module measures the
- time required to perform typical elements of an application.
-
- Text Scrolling displays short, medium, and long lines
- of text using DOS, BIOS, and C library routines.
-
- Text Windows scrolls text through windows.
-
- Graphics Video draws random-sized areas, lines,
- ellipses, and 15 small graphs.
-
- CPU Speed generates and sorts 30,000 integers.
-
- Floating Point performs a Fast Fourier Transform on
- internally generated data.
-
- Disk Speed generates data, indexes, sorts, and
- generates reports.
-
- To run an individual test, move the cursor bar to the test
- description on the main menu and press Enter. Select
- "Run all above tests" to run the entire test suite.
-
- Select "Display and compare results" to compare test results
- with those stored in the benchmark library.
-
- To attach a description to the benchmark results select
- "Describe this machine."
-
- To save the benchmark results select "Save data file."
-
- "Return to DOS" terminates the benchmark suite.
-
- "About these benchmarks" displays this information.
-
- Pressing Esc returns control to the previous menu; if
- pressed when using the main menu, it returns control to DOS.
-
-
- INTERPRETING THE RESULTS
-
- Benchmark results are presented in tabular and graphical
- form. Times presented are in seconds. In each case the
- first column of numbers are the benchmark test times for
- the reference machine, the second are times for the
- comparison machine, and the third is a performance factor.
- The performance factor is calculated by dividing the
- results in the first column by those in the second, and
- expressing the result as a percentage. Thus, if the
- reference machine runs a particular test in 10 seconds,
- and the comparison machine runs it in 5, the performance
- factor is 200%.

- ADDITIONAL INFORMATION
-
- The benchmark results file, and the default benchmark
- reference file can be specified on the PCTECH command
- line by entering:
-
- PCTECH bfile rfile
-
- where bfile and rfile are the respective file names.
-
- The default headings built into the benchmark result
- description record can be overwritten if desired.
-
- By default, Graphics Video tests the the highest resolution
- video mode available. A lower-resolution video mode can be
- tested if desired (or if the benchmark suite is unable to
- detect the proper video mode), by entering the DOS command:
-
- SET HLGRAPH=n
-
- The possible values for n, and associated video modes are:
-
- 4 CGA Medium-res (320x200, 4 color)
- 6 CGA "high" res (640x200, 2 color)
- 8 Hercules (720x348, 2 color)
- 15 EGA Monochrome (640x350, 2 color)
- 16 EGA Color (640x350, 16 color)
- 17 VGA Monochrome (640x480, 2 color)
- 18 VGA Color (640x480, 16 color)
- 19 VGA 256-color (320x200, 256 color)
-
- Disk Speed tests drive C: by default. A different drive can
- be tested by entering the DOS command:
-
- SET HLDISK=x:
-
- before running the test, where x is replaced by the letter
- of the drive to be tested. The drive should have at least
- 100KB available storage.
-
- The name of the default benchmark reference file used by
- "Display and compare results" is stored in XREF.TXT. A
- different file can be specified by editing XREF.TXT.
-
- Print data from the "Display and compare results" print
- option is written to PRN by default. It can be redirected
- to either a serial or parallel printer using the DOS MODE
- command. The printer output can be directed to a file or
- different device by entering the DOS command:
-
- SET PRINTER=filename
-
- where filename is the desired destination of the data.
- Print data is always appended to the file selected.
-
- Additional information about the program and utility files
- that make up the benchmark suite are contained in the
- READ.ME file.
-
- The benchmark programs and results can be downloaded from
- PCTECHline: 301/740-8383 (2400/1200/300 bps, 8 data bits,
- 1 stop bit, no parity).
-
- The design of the benchmark tests, the test methods, and
- how to run the tests and interpret the results is described
- in "High Level Benchmarks," Kent Quirk, PC Tech Journal,
- September 1988, p. 54.
