james michael dupont commented on MESOS-1213:
---------------------------------------------
So I have made progress on this.
Updated the readme with some basic instructions and stats for now :
Profiling
./bootstrap
Enable gprof (and gcov) ./configure --enable_gprof=yes
make
make check
run the test
./src/mesos-tests
use gcov from src
cd src
collect output with xargs and send to gcov
find -name \*.gcno | xargs gcov
You will see currently that only 78% is executed:
Lines executed:77.62% of 28906
Running gprof will show you the stats, but do that to the libtool binary gprof
./.libs/mesos-tests
It will show you the top functions where time is spent, for example :
% cumulative self self total
time seconds seconds calls ms/call ms/call name
