Hi,
I have a code, developed in object pascal, with many classes. The
project is working fine.
Today, I used callgrind (valgrind --tool=calgrind) to see which
function consumes the most execution time and I noticed that the most of
time in my project is consumed by fillchar function.
Incl. Self. Called Function
29.78 29.72 26M SYSTEM_FILLCHAR$formal$INT64$BYTE
19.07 19.07 123M SYSTEM_MOVE$formal$formal$INT64
3.63 3.63 70M SYSTEM_SYSGETMEM_FIXED$QWORD$$POINTER
....
I suspect that the procedure initialization time is added to the first
explicit statement. The initialization can include try-except/finally
blocks, memory allocation (in constructors) or more.
Please create another procedure or method, that uses FillChar not as the
first statement, and test again.
I am not sure what you are asking. The callgrind outputs the call tree
and other information....
Amir
