Try linking Lua without readline and possibly static.
This line:
time for in in `seq 1 1000`; do lua -e return; done
takes
2.0s standard linux build (dynamic, with readline)
1.4s dynamic without readline
0.9s static without readline
on an old 3GHz-P4. 0.02s (20s for 1000) looks like a really slow
machine or something strange's going on.
