Beebe This file collects timing and PostScript version information for a number of local printers and previewers for display of the laserdoctor.ps file. The timing benchmark is for an outline text string that is displayed along the spokes of a wheel; this is only a very modest test of the capabilities of PostScript, but there are surprising variations in the results below. The older Apple PostScript printers lack hardware floating-point arithmetic, so they perform very slowly relative to more modern printers. On several older printers, the page took between 5 and 10 minutes to display; with Ghostscript on a workstation, total display time is well under 10 seconds. For dxpsview on DECstation ULTRIX and pageview on Sun systems, I had to increase the string sizes from 20 and 30 to 128, because both previewers support long font names like -b&h-lucida sans typewriter-medium-r-normal-sans-18-180-72-72-m-110-iso8859-7 ------------------------------------------------------------------------ Printer Vendor and Model PS Version Memory Timing (sec) ------------------------------------------------------------------------ ----- DECstation 3100: GhostScript 54.0 279192 3.08 ----- DECstation 3100: dxpsview 1006.9 8182 1.79 ----- DECstation 5000-200: GhostScript 54.0 279192 1.04 ----- IBM 3090-600S/VF: GhostScript 54.0 279192 0.61 ----- IBM PS/2-70: GhostScript 54.0 646416 29.80 ----- IBM RS/6000-560: GhostScript 54.0 279192 0.62 ----- SGI Indigo 2: GhostScript 54.0 279192 0.85 ----- SGI Indigo R3000: GhostScript 54.0 279192 1.06 ----- Sun SPARC 10/30: GhostScript 54.0 279192 0.65 ----- Sun SPARC 10/30: pageview NeWS 3.100 7053312 2.69 ----- Sun SPARC 10/41: pageview NeWS 3.100 7053312 2.48 ----- Sun SPARC 1: GhostScript 54.0 279192 1.72 ----- Sun SPARC 2: GhostScript 2.6.1pl4 54.0 279192 1.01 ** ----- Sun SPARC ELC: GhostScript 54.0 279192 1.34 b129alw Apple LaserWriter 38.0 239316 114.73 jwb239 Apple LaserWriter II NTX 47.0 1513120 21.65 ----- Apple LaserWriter II NTX 47.0 2957160 17.23 ** jwb321 Apple LaserWriter IIg 2010.113 14900736 8.74 spalw Apple LaserWriter Plus 38.0 239316 115.01 jwb229 HP LaserJet 4M 2011.110 4275840 9.66 imagen Imagen 3320 Imageserver XP 9.1 1024000 42.64 ------------------------------------------------------------------------ ** E-mail from Reg Clemens , Sat, 13 Nov 93 17:57:54 MST
