I have an Avocet old compiler , DOS version, which does not run on dos windows in WinXP, but runs fine with DOSbox 0,70 on winXP, but very slow : a compilation which takes les than 1 second in a W98 window takes 25s on the same computer (I have dual boot) in dosbox with windows XP. The computer is AMD 64 3GHz, 1G ram. I have allready disabled sound etc ... , here are some parameters (file dosbox.conf attached) :

I would appreciate any idea to improve speed !

machine=vga
memsize=256
frameskip=20
aspect=false
cycles=max
cycleup=500
cycledown=20
nosound=true
mpu401=none
sbtype=none
gus=false
pcspeaker=false
joysticktype=none
xms=true
ems=true
umb=true
keyboardlayout=none

You're aware that dosbox emulates a full system, right?

Yep, core=dynamic, maybe set cycles to a high value, instead of max.

You really shouldn't mount the root of C:\ and you certainly should not add your Windows directories in the path. You are asking for trouble,
All this keyboard stuff is really not necessary (does it even work?), just set keyboardlayout to the one you need
