(I have a local hack that adds a new malloc option to explicitly memset() new pages allocated via mmap() that gives the same benefit without the junking overheadon each malloc() / free(), but it does increase physical RAM usage.) John, A couple small steps have been taken toward eliminating the need for this hack: the addition of the page size index field to struct vm_page and the addition of a similarly named parameter to pmap_enter(). However, at the moment, the only tangible effect is in the automatic prefaulting by mmap(2). Instead of establishing 96 4KB page mappings, the automatic prefaulting establishes 96 page mappings whose size is determined by the size of the physical pages that it finds in the vm object. So, the prefaulting overhead remains constant, but the coverage provided by the automatic prefaulting will vary with the underlying page size. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

I am the author of the post referred in the previous message (Wordpress brought me there). I am liking FreeBSD, and I'll probably migrate soon my current Debian server to it. One of the reasons that I enjoyed FreeBSD is because it is similar to Arch Linux (my current preferred Linux distro) in various ways. Anyways, I just wanted to indicate this [2] link to you. It is a good resource comparing different package manager commands. Right now it does not include FreeBSD's pkg, however I highly encourage you to add one more column to this table, featuring it. There is no problem that pkg is not a Linux thing. Also, I am interested in the direction the original thread could go. As a almost-2,5 years Linux user, I could have discovered FreeBSD before. One of the reasons that I haven't paid much attention to it in the past was just because I didn't know that it had a large community. I thought it was small, not much significant. I'm still confused about the difference between the several BSDs out there (Open, Net, DragonFly, etc) and the relative size of each community, however at least I can see it is significant :) [1]: https://lists.freebsd.org/pipermail/freebsd-current/2014-July/051429.html [2]: https://wiki.archlinux.org/index.php/Pacman_rosetta Thiago, I really liked the blog articles you wrote: http://thiagoperrotta.wordpress.com/2014/07/20/here-be-dragons-freebsd-overview-part-i/ http://thiagoperrotta.wordpress.com/2014/07/21/here-be-packages-freebsd-overview-part-ii/ and you have very good suggestions.

I recently moved back to FreeBSD after 14 years on debian, and was shocked at how great poudriere + pkg is for maintaining a consistent set of packages for a cluster of systems. (I know it's pitiful compared to the cloud, but I've got 3 FreeBSD and 3 debian-testing atm, and two of those debians are in danger of forced religious conversion. :-) The main reason I moved to debian in the first place is I was working in high user-space and I needed office apps (egads) working consistently and reliably through upgrades, and the ports system then was not up to the job. It is now! Basically, poudriere + pkg is debian apt-file + apt-cache + apt-get + approx with the added benefit of site specific, port-specific options. Maybe like arch? So I would be very willing to contribute to this project, if that makes sense. Best, Russell (what list should this move to?
