I have done some more timings:
Timings, appending 100_000_000 uints, seconds:
DMD 1.042: 7.51
DMD 1.042, ArrayBuilder: 1.81
DMD 2.029: a lot
DMD 2.029, Appender: 22.83
I'm not sure on what machine you test, but on my (crappy old) laptop,
your Appender example completes in 4.95 seconds. Are you sure you are
measuring the right thing?
