Maybe this is relevant to my poor performance then but perhaps it’s just the
way the time profiler works? It’s telling me the program is spending 16% in
system_delocked which seems extreme.
See if I have a dynamic array and call arr[0] := xxx then those functions will
be called (or FPC_DYNARRAY_ASSIGN)? I also have a dynamic array in an object
which is passed a function parameter, but not by value so that doesn’t fit your
description.
