I was wondering what happened because the tested DOSBOX 0.74-3 (not tested older versions) shows a strange behaviour while executing a small benchmarking program.
This small benchmarking program was a part of a MASM 5.10 sample series, written by myself.
I tested it with real PCs, with PCem, and with DOSBOX.
DOSBOX was slowing down significantly while displaying an increasing amount of single (colored) chars, using the INT 10 function 09h.
You can look into the program source code as well, see the link above.
I was curious what is the reason for that.... any hints ?
