Benchmarking procedures used for Unix Today! 5/27/91 X terminal review.

Necessary software:

1. x11perf version 1.2 --  available from UUNET in /X/contrib/x11perf.tar.Z
   x11perf requires the fonts 6x13, adobe-times-medium-r-normal--10-100-75,
   and adobe-times-medium-r-normal--24-240-75.

2. x11perfcompDR version 1.01 -- available on UUNET in  
   /unix-today/benchmarks/x11perfcompDR

3. If you want to use our data files, they are on UUNET in
   /unix-today/benchmarks/52791.bench.tar.Z


Our lab setup:

The host:  SparcStation 1 with 16Mbytes of RAM and
2x105mb Quantum internal hard drives. 32Mbyte swap 
partition. Color monitor.  The official Sun designation for
this machine is "Sun 4/60-GX-16-P3".  It's running SunOS 4.1.1
with XTech's X11R4 server Release 2 available for compiling X 
client software. OpenWindows is not loaded.

Thinwire connection directly to tested X terminal. Terminated
at both ends.

The Samsung and HP terminals both have 6Mybtes of RAM. The
DEC VT1300 and Micronics have 8Mbytes.

The following X terminals were tested with these versions of 
X server software [the DEC, Micronics, and NCD results are from
the 4/1/91 issue and are contained in the 4191.bench.tar.Z
archive]:

color:

Samsung SGS-17C      -- 1.7X beta PROM server.
HP 700/RX Model 16Ca -- A.01.15 beta version download server.
DEC VT1300           -- VAXELN version 1.0 "field test" software.
Micronics MaxTerm 4X -- ROM version 1.0.9A. 

monochrome:

NCD19                -- ROM version 2.2.1


Preparing the X terminal for benchmarking:
  

  1. All color systems are set to 8-bit color, if that's not
     the default. The Micronics is capable of 24-bit color.

  2. Backing store is turned off on all terminals through the
     ROM setup.

  3. Save unders are disabled on all terminals through the
     ROM setup.

  4. On the NCD, arc caching is turned off.

  5. No window managers are running. No clients other than
     x11perf are running.

  6. All screen savers are turned off with xset or the ROM
     setup.

NOTE:  x11perf tries to turn off save unders, backing store, and
screensavers when it starts up, however, some X-terminals
can override those actions via ROM setup options.

X11perf version 1.2 was used for testing. 
For monochrome terminals the following command line was 
used:
    x11perf -all -display 192.9.200.8:0.0 > terminal_type.out

For color terminals the following command line was used: 

    x11perf -all -display 192.9.200.8:0.0 -fg blue -bg red > terminal_type.out

Results were summarized using x11perfcompDR on the
SparcStation:

    x11perfcompDR terminal_type.out reference.out > terminal_type.out.comp

The reference system for our tests was the NCD19.
