As I wrote in my previous mail, in tested program segment is about
200000 times called INT0x16 Fn 0x11 : Check_Enhanced_Keystroke.
In corresponding dosemu routines in "base/bios/int16.c" are called
some delay functions - maybe these may add some delay to program
execution.
On my system CLK_TCK=100 (ticks/sec), thus JIFFIE_TIME=10000 and
INT2F_IDLE_USECS=80000 (=> 80msec delay).
But as I wrote, on my faster PC exec time was 3 sec, thus delay
added in INT16 can't be longer.

Bart Oldeman probably can say more about this.
