Igor,

I got similar results to what you describe.
Below are runs for BenchPress.js, speed.js
and all_bench.js. I did 3 runs for each test
on each engine, took the average, calculated
the ratio, with SM as reference (1).
Rhino JIT beat SM in only one case (BenchPress.js)
and not in a ratio enough to warrant engine switch.
I used jdk1.5.0_01 for Rhino latest, SM also latest.
Thanks,

Celso
