Release 4.17
BENCHMARKS
The data were obtained with the utilities HLTEXT.EXE and HLWINDOW.EXE of the
PC TECH JOURNAL benchmarks 1.0 (c) 1988 Ziff Communications Co., BENCH24.EXE
of the PC MAGAZINE benchmarks 5.0 (c) 1989 Ziff-Davis Corp., and VIZMARK.EXE
version 2.22 (c) 1991 F.M. de Monasterio. These data represent the mean of 5
sequential runs of each utility, after the initial run (that was discarded),
expressed as the factor in accelerating operations relative to the benchmark
results obtained without a video accelerator. In other words, the higher the
factor the shorter the actual benchmark times for a given test.
The accelerator being tested was installed as the only resident program that
intercepted the BIOS video interrupt in:
1. 25-Mhz, 486 computer with a 32-bit bus, an Award BIOS version 3.12.00d-
21, and a 16-bit nonplanar VGA adapter.
2. 25-Mhz, 386 computer with a 32-bit bus, a Phoenix BIOS version 1.10 10a,
and an 8-bit nonplanar VGA adapter.
3. 16-Mhz, 386 computer with a 16-bit bus, a 1984-IBM AT BIOS, and a 16-bit
nonplanar VGA adapter.
4. 10-Mhz, 8088 computer with an 8-bit bus, a 1988-EPSON BIOS, and an 8-bit
nonplanar VGA adapter.
A 25 row, 80 column screen was used in all machines. The 32-bit bus machines
were run under IBM PC-DOS 3.30 (386) and MS-DOS 4.01 (486) while the other 2
machines were run under COMPAQ MS-DOS 3.31 (386 and 8088). All VIz versions
being tested used word OUT addressing. The BIOS (video) was not remapped to
faster RAM in the 386 and 486 machines; in fact, since use of a 386-specific
memory manager can sometimes decrease video performance, these machines were
tested without such a manager being installed.

NOTES:
(1) ZENO.COM (version 2.20) could not included in the above comparisons
because its 'teletype' service garbled the DOS prompt/command line.
(2) Copyright 1986 T. Overfield (version 1.00).
(3) Copyright 1987-89 MultiSoft Corporation (version 1.05).
(4) Copyright 1985-87 Golden Bow Systems (version 1.06).
(5) Copyright 1986-87 Soft Programming Services (version 1.04).
(6) Written by E. Tauck (version 1.00). Could not use the faster version
WARPF.SYS or WARPVF.SYS because testing int-29h services via VIZMARK
crashed the machine (these two CON device drivers themselves use int
29h for 'fast' output, but rely on the internal CON driver to handle
this interrupt). WARP provides rudimentary ANSI support.
(7) Sum of the acceleration factors divided by the 12 tests.
(8) Mean video acceleration factor divided by the resident size (rounded
to the next larger paragraph [16 bytes] boundary) in kbytes (1 kbyte
= 1,024 bytes). This is an approximate index of the effectiveness of
the resident code in implementing video acceleration.

NOTES:
(1) Relative to ANSI.SYS distributed with COMPAQ MS-DOS (version 3.31).
(2) Version 4.20; the resident accelerator uses 912 bytes of memory; ANSI
plus Cursor service resident size is less than 800 bytes. Notice that
DOS acceleration switch is off (/Z-).
(3) Copyright 1989 Ziff-Davis Corp., Author: M.J. Mefford (version 1.20).
Switch /B0 yields the smallest resident size; part of such a resident
handles keyboard remapping services (not included in the benchmarks).
Switch 'SLOW' generates an output slower than that of ANSI.SYS alone.
Resident can be turned off and removed from memory.
(4) Copyright 1986, D. Kegel (version 2.2). Includes a keyboard remapping
service. Driver cannot be turned off or removed from memory.
(5) Copyright 1986, 1987, T. Hanlin III (version 1.2). Does not include
keyboard remapping services. Driver cannot be turned off or removed
from memory.
(6) Copyright 1989, 1990, Luns Tee (version 1.1). Also includes an Avatar
level 0 handler. Used ZAVTNK.SYS, which is smaller than ZAVT.SYS and
has the keyboard remapping service disabled. Driver cannot be turned
off or removed from memory.
(7) Sum of the acceleration factors for DOS, CON, and ANSI divided by 3.
(8) Mean DOS/CON/ANSI output factor divided by the resident size (rounded
to the next larger paragraph [16 bytes] boundary) in kbytes (1 kbyte
= 1,024 bytes). This is an approximate index of the effectiveness of
the resident code in implementing this video output subset.
