Linux host, WinXP guest. With kqemu acceleration enabled it runs
significantly slower, not faster as one would expect. /dev/shm is
mounted. max-user-freq set to 1024.
Any ideas ?

Many possibilities here..... what kind of applications do you run
inside the Windows guest?
essentially, kqemu helps if there aren't many traps which results into
code translation or guest+host are using same data bus width (not sure
if it's the correct term, i.e 32 bit guest on 32 bit host...).
see kqemu documents about technical limitation and assumption on codes
that can be executed directly by kqemu.
regards,
Mulyadi.

No applications, just windows boot.
