QuickerGraf 1.0 was released together with a performance benchmark that compares the speed of various operations with QuickerGraf on and off. Timings are reported as percentages: (time without QuickerGraf)/(time with QuickerGraf) * 100% Figures over 100% indicate an improvement due to QuickerGraf and figures below 100% indicate a detriment due to QuickerGraf. For example, a result of 2441% shows that QuickerGraf is more than 24 times as fast as native QuickDraw for that particular operation in that particular mode. Since reports have varied as to whether QuickerGraf is beneficial in any mode but 8-bit color, I ran the benchmark in every mode available. Here are the results: Test: Colors: 256 16 4 2 simple pixel pattern fill, no clipping 319% 100% 100% 102% simple pixel pattern fill, region clipped 334% 243% 196% 150% fill oval, unclipped, simple pattern 251% 173% 141% 118% fill roundrect, unclipped, simple pattern 291% 201% 163% 133% unclipped, unmapped, copy mode copybits 170% 99% 101% 97% copybits with color mapping 310% 99% 99% 239% 1 to 8 copybits, no clipping 196% 98% 98% 100% addover fill mode, simple pattern 1088% 100% 100% 100% blend fill mode, simple pattern 2441% 100% 100% 100% transparent fill mode, simple pattern 924% 99% 99% 100% hilite mode, region clipped 258% 99% 100% 120% Ephraim Vishniac ephraim@think.com Thinking Machines Corporation / 245 First Street / Cambridge, MA 02142-1214 On two occasions I have been asked, "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?"
