I found it's not that easy to get a consistent time 
on XP, but here goes:

On my new P4 1.8 GHz, 512K cache machine
interpreted sieve using ex: 29819.5
Translated sieve with Watcom: 92726.7

On my older 350 MHz, 512K cache machine I get:
interpreted sieve using ex: 6006.7 
Translated sieve with Watcom: 21229.2

interpreted P4 is faster by 4.96x
translated/compiled, P4 is faster by 4.37x

1800/350 = 5.14x

so the P4 is not living up to what you'd expect
based on MHz alone. I suppose there could be
some cache misses and the cache memory is not 5x faster.
