With slight modifcaition to capture the timestamp of the
request on the server:
import std.datetime.systime : Clock;
auto tm = Clock.currTime().toISOExtString();
writeln(tm, " My Thread Id: ", to!string(thisThreadID));
// simulate long runnig task
Thread.sleep(dur!("seconds")(3));
if (req.path == "/")
res.writeBody(tm ~ " Hello, World! from " ~
to!string(thisThreadID), "text/plain");
Launch two parallel curls.. and here is the server log..

PS: Your top posting makes reading your replies difficult
I have change my example a little:
case "/": res.writeBody("Hello World " ~ to!string(thisThreadID),
"text/plain");
And I get this (siege -p -c15 0b -t 10s http://127.0.0.1:3000 |
grep World | sort | uniq):
Hello World 140064214951680
Hello World 140064223344384
Hello World 140064231737088
Hello World 140064240129792
Hello World 140064248522496
Hello World 140064256915200
Si I get six different thread ids, which is OK because I have 6
cores
