Here's some timings with and without scrolling and using both Type and Copy. Leaves me wondering what Type is doing extra. I ran all these tests at the same time with my system load unchanging. The times were very consistent. Let me say to save space below that the PD Blitzfonts produced times with Pearl that were indistinguishable from those of the usual Text routines with Pearl or Topaz. For the purposes of producing something that would take long enough to get on the screen for a decent timing and still not scroll I made a file with the following repeated 50 times [H[J 20 lines of 72 a's That is 50 pages of a's with the page cleared at the start of each page. A total of 73350 bytes counting newlines. Using 'Type' took 1:09 without BlitzFonts and :54 with it. Using 'Copy file to *' took :32 without BlitzFonts and :17 with it. When I reinstated scrolling by eliminating all the lines and adding enough 'a' lines to bring the byte count back up to 73350 I got the following results Using 'Type' took 1:32 without BlitzFonts and 1:17 with it. Using 'Copy file to *' took :56 without BlitzFonts and :41 with it. Now I would say that the last improvement is adequate, being a 37% percent increase so even with scrolling Copy sees a benefit from BlitzFonts. And the result for Copy with no scrolling is a 88% increase -- quite nice. But with NO SCROLLING the best Type can do is a 28% increase. Of course Type is much smaller than copy but I always figured that was because it didn't have to interpret file name patterns. Is this smallness my reward? Or is Type deliberately SLOWED DOWN because its authors figured people would be trying to read the text as it came by ? (Not a bad reason.) And what out there enjoys the increases of 400% I have seen quoted? -- Charles Cleveland EDU: chas@ss.physics.gatech.edu Georgia Tech School of Physics UUCP: ...!{akgua,allegra,amd,hplabs,ihnp4, Atlanta, GA 30332 masscomp,ut-ngp,rlgvax,sb1,uf-cgrl, unmvax,ut-sally}!gatech!gtss!chas
