P.S.: Funny fact, theide 64 optimal size is 15920KB, speed is 17354KB. I guess I will drop this confusion soon...

I tested it too and it is 400 KiB on my 32 bit exe.

But a round trip (and not necessarily round trip, works one way too) conversion from Int to String is about 3 time "slower" on size for 100 million iterations than on "speed". And this with a bunch of hacks I added to speed it up. Without, it is even slower. So I'm sticking with -O2 from now on.

I would have never used anything else but TheIDE made this choice for me.

Optimal means optimal.
