<p dir="ltr">Having the "production ready" make target be "make profile-opt"<br>
doesn't strike me as the most intuitive thing in the world.</p>
<p dir="ltr">I agree we want the "./configure && make" sequence to be oriented<br>
towards local development builds rather than highly optimised<br>
production ones, so perhaps we could provide a "make production"<br>
target that enables PGO with an appropriate training set from<br>
regrtest, and also complains if "--with-pydebug" is configured?<br>

<p dir="ltr">Agreed. Also, printing a message out at the end of a default make all build suggesting people use make production for additional performance instead might help advertise it.</p>
<p dir="ltr">make install could possibly depend on make production as well?<br>
