I have done some benchmarks on nvidia hardware. In theory you may be right
but in practice most drivers are optimized for glDrawElements and not 
display
lists. This is at least the case on nvidia. glDrawElements was a LOT faster
compared to display lists last time I benchmarked it (which was some 
time ago
so current drivers may have different results).
