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.
