I'm not sure what you mean by "the maximum rate I get is ~33Mbps".

Are you trying to actually _measure_ it? Then, on a decent platform, you
should probably get many *gigabits*.

Or are you trying to look at the rate in "iw station dump" or in
radiotap? Then you should see higher rates since hwsim is configured to
pretend to have 4 spatial streams (IIRC)
