This patchset implements profile-guided-optimization (PGO) for Python 3. The
implementation is very similar to my previous patchset for Python 2.7.
PGO for python3-native is one simple patch. PGO for target python3 is more
complicated and follows the lines of Python 2.7:
1. add new python-profile-opt3 recipe that is a special version of python3
with profile instrumentation enabled
2. add new do_profile3 in python-pgo-image for running the python3 profile task
in the target
3. enable usage of profile data in python3 do_compile
Configration variables for controlling the feature are:
PYTHON3_PROFILE_OPT - set to "1" to enable PGO on python3
PYTHON3_PROFILE_TASK - profile task to run for python3
PYTHON3_NATIVE_PROFILE_OPT - set to "1" to enable PGO on python3-native
PYTHON3_NATIVE_PROFILE_TASK - profile task to run for python3-native
Benchmark results from my i7-3770K are found below.
python3-native:
pystone: 118288 -> 138026 pystones/s (+17%)
pybench avg: 3428 -> 3118 ms (-9%)
regrtest time: 598 -> 550 s (-8%)
python3 (target):
pystone: 1531 -> 1616 pystones/s (+5.5%)
pybench avg: 215901 -> 207498 ms (-3.9%)
regrtest time: 8355 -> 8157 (-2.4%)
Again, these are just ballpark figures from few test runs.
