On my Windows box, the following program
import std.stdio, std.container, std.range;
void main() {
enum int range = 100;
enum int n = 1_000_000;
auto t = redBlackTree!int(0);
for (int i = 0; i < n; i++) {
if (i > range)
t.removeFront();
t.insert(i);
}
writeln(walkLength(t[]));
//writeln(t[]);
}
runs in about 1793 ms.
The strange thing is, if I comment out the writeln line, runtimes
are in average *slower* by about 20 ms, with timings varying a
little bit more than when the writeln is included.
How can this be ?
