One thing you might want to check (I'm not sure, offhand) is whether 
repeated use of this macro, even when accessing the same feature, will 
consume some limited TeX resource, such as font numbers or whatever. It 
might be necessary to make it "cache" the \font definitions it creates, 
and re-use them when the same combination of features comes up again.
