Emulated 65C816 speed or emulated IIGS speed?  There IS a difference.
Many benchmarks just sit there counting loops.  On a IIGS, this is an
accurate way to determine CPU speed which on a real IIGS correlates
with computer speed.  On an emulator, things are different.  Run a
counting loop and what happens is that the emulator for the IIGS is
mostly just running the 65C816 emulation and thus can benchmark
suprisingly fast.  However, run a program, play music, access the disk,
redraw the screen.  Anything that forces the emulator to emulate the
IIGS' hardware actions and the speed falls dramatically.

That's why XGS' bootlog file lies and so do benchmarks run under
emulation.  The speed you notice when RUNNING IIGS applications
on an emulator will be slower than the speed the emulator
benchmarks at.
