True! When I disabled GC 30_000_000 cycles are on 8s instead of 400s.
Good to know that if I want to do such kind of operation in large
amount it is good to switch off the GC.

Just for comparing, i've done some research with other languages with
default GC settings and the (i * 0.3).to_i operation
ruby 1.9.2 400s
ruby 1.9.3 150s
python3 33s
perl 25s
lua 12s
jruby1.6.2 5s

and c with -O3 0.08s :-)
