Any reason why neither has been committed? I have already updated Tim's patch to match latest -CURRENT: http://people.freebsd.org/~delphij/patch-hashpid I haven't actually checked the patch at this time, though. But even if there is something strange happend it should not be so hard to check the recent commit logs to respective files. I plan to update the NetBSD allocator as soon as I have an entire chunk of time, even if it was not chosen as the final version of our PID allocato= r, as previously inclined in the discussion, I'd like to keep it as a part of my private collection ;-) What we should pay extra attention is that while both patch could lead to a performance gain in microbenchmarks, there is also chance that they slow down something else. Carefully investigate of these issues are required before we actually commit one of the two. I don't have much time to deal with this topic in the near future. So it's up to Tim or other fellow committers' decision whether to commit one of the two, with or without change, but it's important that we have done some actual test before doing that =3D-) Cheers, --=20 Xin LI <delphij frontfree net> http://www.delphij.net/ See complete headers for GPG key and other information. --envbJBWh7q8WU6mo Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQFB4CrQ/cVsHxFZiIoRApRTAKCLvS/PEfxbp87Ud0ybbPVhk+rbgACdGTGJ 2CSbZCNs+Z16LIXzSnuhJmA= =u7gA -----END PGP SIGNATURE----- --envbJBWh7q8WU6mo--
