You only test libregrtest.main and libregrtest.runtest_mp modules which don't
execute code. Does it mean that running tests is useless to train the PGO?
New submission from Dong-hee Na :
Compiling CPython with the PGO option is good for CPython performance but
compile time is very painful since PGO profiling is executed with a single
thread.
When I tested with run -m test --pgo -j8, it doesn't affect to optimized result
with fast build time.
