RE: Emulator vs simulator performance
Performance measurents with Emu71/Win until v1.11
J-F Garnier made some performance tests with Emu71/DOS and Emu71/Win and detected a performance catastrophe inside Emu71/Win until v1.11 (actual version) in connection with the BASIC GOTO command. Emu71/DOS is not affected. A loop with GOTO where you expected an execution time at full speed of ~0.08s takes ~9s, whereas the same loop at "Authentic Calculator Speed" takes ~20s. This behavior is caused by annunciator settings combined with the display annunciator update which takes quite long. TNX to J-F Garnier for this detection. The problem will be fixed in a next version, so take care when you do performance measurements with Emu71/Win until v1.11 with a massive use of GOTO loops. |
