I isolated the xml parsing and wrote a test program. It turned 
out that the xml parsing is the culprit.

The average after running it 0..10 times in a loop (if I ran it 
100 times, it wouldn't look much different):

dmd 2.063
Average time: 2233 msecs

ldc2
Average time: 10.2 msecs

I used StopWatch based on this example 
(http://dlang.org/phobos/std_datetime.html#StopWatch).
