I had the same experience with OpenBSD for sparc64, also fast to
install. The problem is that this is due to simplicity and amount of
data/bins to install and not due to fact qemu got miraculously faster
with *bsd sparc64 bins I'm afraid. IIRC mu compile nbench2 benchmark
reveals +- the same performance on sparc64/openbsd and on
sparc64/sparc32-userland debian.

need to check the installation size - but NetBSD was "full install (without x)" and
debian was just "basic system utilities"

NetBSD comes with gcc with this installtion type, debian not
