Hi Eric
Times are just rough ballpark figures for comparison and specific to one
of my primary applications, a command line assembler. In this test case,
the assembly code consists of about 150 modules (files) and amounts to
slightly over 22K lines. Timing is done using 4DOS's TIMER command. I
take the worst times for each and calculate speed and then the best
times for each and calculate times.
Some specs below. Please let me know if there is any other info you need
and how I get it.
MS XP PC
Hardware. Year approx. 2006. HP NC6320 Notebook. CPU Core 2 Duo T7200 @
2GHz. RAM 2GB Dual channel DDR2 @ 332 MHz. Storage SSD.
OS. Win XP Prof. 32bit SP3. Partition size. Drive C: 50GB NTFS
MSDOS 5 with 4DOS
autoexec.nt
C:\PROGRA~1\Tame\tame-nt.com
config.nt
dos=high, umb
device=%SystemRoot%\system32\himem.sys
device=%SystemRoot%\system32\ansi.sys
Linux PC
Hardware. Year approx 2012. Toshiba Satellite C850-F21E Notebook. CPU
Intel Core i3-2350M. 2.4GHz. 64 bits. RAM. 4GB. Storage SSD.
OS. Linux Mint xfce 22.1 64 bits.
Both QEMU and DOSEMU2 use KVM. Two instances of ' auto' replaced with
'kvm' in the global settings file /etc/dosemu/dosemu.conf for DOSEMU2 .
No speed improvement, set back to 'auto'.

Please explain how you measure speed and which hardware
you used for dosemu2, qemu and "xp vdm", including which
types of disks and partition etc. Thanks :-)
