Right, but it's not twice as slow :-) Worse... It's at least 50-100 times
slower.
Weird.
I will have to do some bench marks. I just thought that if there was
already a string
concatenation happening, that an additional concatenation would cost me
twice as much
time, but not 50-100 times. Plus, the second concatenation is a small
concatenation.
It's only two characters in length (#13#10) whereas the Line is much bigger.
Use a good profiler like valgrind/kcachegrind to see where the most time is
spend. Also from your code it is not clear what kind of strings are used.
There is a huge difference between shortstring and ansistrings regarding
performance.
