Benchmarking procedures used for Unix Today! 4/1/91 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/4191.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 [except for DEC and IBM which had an additional
host connected for server downloading].

All X terminals have 8Mbytes of RAM except the GraphOn 
which only comes with 1Mbyte. The amount of I/O RAM
varied somewhat. The Tektronix has 4Mbytes of I/O RAM.
The IBM has 1/2 Mbyte. Others had small amounts. The I/O
RAM is in addition to the 8Mbytes.

The following X terminals were tested with these versions of 
X server software:

color:

DEC VT1300           -- VAXELN version 1.0 "field test" software.
IBM XStation 130     -- Xstation Manager version 1.2.  
Micronics MaxTerm 4X -- ROM version 1.0.9A. 
Tektronix XP29       -- ROM version 3.0
NCR XL17C            -- ROM version  01.01.00.37R-CC

monochrome:

Samsung SGS19        -- AGE code ROM 1.0X2
NCD19                -- ROM version 2.2.1
GRAPHON 21           -- Host version 3.0.4. Terminal revision 1.0.3
Visual X-19 Turbo*   -- ROM version 3.0
HDS V19 Plus*        -- ROM version Beta 2.3

*[actually 2-bit greyscale systems]

Preparing the X terminal for benchmarking:
  
  1. The 2-bit greyscale systems, Visual and HDS, are set
     to 1-bit monochrome mode through the ROM setup.

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

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

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

  5. On the IBM and Micronics, all virtual memory effects
     are turned off. 

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

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

  8. 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.
