I have modified the code:

import std.stdio: File, writeln;
import std.conv: to;

int process(string fileName) {
    int total = 0;

    auto file = File(fileName);
    foreach (rawLine; file.byLine()) {
        string line = to!string(rawLine);
        total += line.length;
    }
    file.close();

    return total;
}

void main(string[] args) {
    if (args.length == 2)
        writeln("Total: ", process(args[1]));
}


The run time is 1.29 seconds, showing this is equivalent to the idup.
