Hi,
I noticed quite a difference between the two method who "looks" the same to me. Is it normal ?
Normal. to:do: is lnlined (compiled as jumps in the bytecode), whereas timesRepeat: is a message send with a closure activation. Marcus fun is the difference between: (1 to : 10000) do: and 1 to: 10000 do: one is compiled to jumps, the other not and in addition creates a temp collection. Marcus
I use a rc image (haven't tested in squeak). And it's the same on windows and linux.
count := 0. [1 to: 10000000 do: [:i | count :=count + 1]] timeToRun." 677" count := 0. [10000000 timesRepeat: [count := count + 1]] timeToRun" 2571"
If not normal, I'll open a issue.
Thanks
