Up to now the results are promising:
Table 1 shows the results (score, higher values are better). Compared to Sun's HotSpot Client VM (1.3) the code generated by JaRTS was about 20% faster for the logic test. The other tests ran about 58% (sieve test) up to 366% (loop test) slower. Compared to Sun's CVM [20] (on which the TimeSys real-time reference implementation is based) JaRTS is 3 times up to more than 15 times faster.
Improvements of the JaRTS performance should still be possible since there was no effort in optimizing performance, yet.
