Greetings,
The following webrev contains changes to improve the performance of
python 2.6 and python 2.7 by using profile-guided optimisation during
compilation:
6771457 explore compiler performance improvements for python
https://cr.opensolaris.org/action/browse/pkg/swalker/pyopt/webrev/
Build workspaces can be found on coupe (x86) and kodiak (sparc) under:
/builds/swalker/userland/components/python/python2(6|7)/
Using a profile-guided build for python2.6 and python2.7 along with
raising the minimum processor target for compilation significantly
improves the performance of pkg(5), and likely all Python programs based
on the results of pybench comparisons.
