our buildbots are setup to configure --with-pydebug which also unfortunately causes them to compile with -O0... this results in a python binary that is excruciatingly slow and makes the entire test suite run take a long time.
given that nobody is ever going to run a gdb or another debugger on the buildbot generated transient binaries themselves how about we speed all of the buildbot's up by adding CFLAGS=-O2 to the configure command line?
Sure, the compile step will take a bit longer but that is dwarfed by the test time as it is:
http://buildbot.python.org/all/builders/AMD64%20Ubuntu%20LTS%203.x/builds/32... http://buildbot.python.org/all/builders/ARMv7%203.x/builds/7 http://buildbot.python.org/all/builders/AMD64%20Snow%20Leop%203.x/builds/639
It should dramatically decrease the turnaround latency for buildbot results.
maybe check if the compiler understands -Og (GCC 4.8), and use that? Otoh, it would be good to check with -O2 or -O3 too, common values used when building python for production use. Matthias
