The results are in:

I'm running Linux FC4 on x86_64

The RTL results are quite amazing with -O3 optimization
1000000 records added
2000000 records added
That took just 320ms

RML RTL
-O3 1260ms 320ms
-O2 3200 ms 780 ms
w/o 21230ms 13760ms

Maybe there is something hampering RML 64-bit performance, as my best RML
result on a 3GHz box doesn't differ much from Calum's 1.7GHz laptop !

I would like to see a more complex test with insert, select and delete, e.g.
something like the resorce reservation system in
http://www.infosys.tuwien.ac.at/NewsCache/pstl.html#evaluation

where you have insertion, iteration, lookup/select and deletion
