Transparent Superpages was in FreeBSD for a few years. I would like to know if there is any benchmark or real world performance experience about this setting. 2. I have seen somewhere that non-transparent superpages was being developed in HEAD too. Any insight on it? Please correct me if it is not the case.

Please correct me if it is not the case. By "non-transparent" do you mean explicit huge pages API which allows them to be allocated on-demand rather than heuristically, such as was implemented in Linux for at least 8 years (http://goo.gl/8qZX4D, https://lwn.net/Articles/375096/) and supported by major software products (http://goo.gl/prxjjo, http://goo.gl/fQOLwO, http://goo.gl/pr7Tbb, http://goo.gl/Y9qtWk, http://goo.gl/M0l7LL, etc.)? I haven't heard about it (but I hope I'm wrong :) ). ------enig2VGTJGUDTUOBCQUIXXHVB Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlI4fggACgkQ/QjVBj3/HSynRACfX8k+GiFrLBHZdZ0eb8DCxZVJ fLYAn2iDGNGjvvuRXlApKQS5NjVMjWqk =4wGF -----END PGP SIGNATURE----- ------enig2VGTJGUDTUOBCQUIXXHVB--
