I have been profiling Wesnoth with Shark and Instruments on OS 10.5,
the results which still need a bit of mining and statistical analysis
show that Wesnoth spends a majority of its time ( ~ 85% ) in the
graphics and audio routines, a large amount of time blocking in the
main loop ( between ~3% and ~7% ), and lastly about ( ~ 3% ) combined
allocating std::string, copying std::strings and comparing
std::strings in maps. Most other operations weigh in under 0.1%. These
numbers, as I said need refining, and as I only have had time for a
sample size of three runs ( they take quite some time ) they may
change.
Before I do anymore runs, do these numbers line up roughly with
expectations and previous analysis?
first and formost, thanks a lot for the job
I wanted to do something like that but real time always comes in the
way.
If you can post your raw data somewhere that would be great (I only
use gprof, I don't know if your tool provides a "raw output" that we
could use)
I am very interested in the time spent in the graphic routines,
since i'm responsible for the high level ones... I have a question
for you though :
how did you test (what kind of run, did you have an AI, was it
network play...)
When I post data it will have a full description of the test
environment and scenario, but for now here is a brief:
I was playing the first scenario in 'Heir to The Throne' on the lowest
difficulty. I was skipping player turns, and would test for 20
minutes, which with cpu and memory profiling would be three or four
rounds. I skipped player turns because it borders on unresponsive
while profiling memory.
If I find the time I will see if I can produce some human readable
output today.
that's very important for us to analyze your result (obviously) and
will help us provide with other test cases for further analysis.
These results match our "gut feelings" but little has been done so
far WRT basic CPU performance, and there is probably a lot to gain
there...
I really hope to hear some more from you, possibly with some patches
submitted to correct the worth offenders...
Cheers
