I was curious so I quickly ran up some big sieves on local machines.
Standard (-O) optimisation, Release 3.5 SUN3 and Release 3.2-Sys4-R2 SUN4.

For the SUN4 it is necessary to print out the iteration count variable at the
end when using -O otherwise the compiler optimises out the iteration loop and a
single iteration gives zero time!  (I used 100 and divided by 10 to get the
above results).
