Is there any reason to think that the speed difference is due to features of
the language? How about the fact the verilog has a larger market share then
vhdl, and so it pays for simulator vendors to concentrate on optimizing
their verilog simulators?

On the other hand, is there any reason to think that a vhdl netlist could be
simulated faster than a verilog netlist? Is there anything about vhdl that
makes it more amenable to optimization than verilog at the gate level?
