    too early ?

    adding discard options to ext4 on SSD is not a good idea.
    when removing a lot of small files (make clean ?), it can freeze a computer for 5-10min.
    it's the case on my laptop (quad-core with 6G RAM), and a better method is to add fstrim to a crontab.

    when I say freeze, I mean all keystroke/click are delayed by 30-40s, so it's completely unusable.

      I don't have this problem on my desktop (256 GiB Samsung 840 Pro, i7-2600 K, 8GB of RAM, running Xubuntu 13.10). I don't notice anything like excessive RAM usage or something like that.

        So why could Windows add this in 2009?

          I am with Calinou, I have never had that issue. And even after months of updates apt-get clean is instantaneous. I do not compile a lot, and my projects are relatively small, but make clean is also instantaneous for me.

          I am using Debian Sid/Jessie not Ubuntu.

          For 99% of users discard is a good idea. For people like you, you are smart enough to edit fsatb and use crontab instead.

            I use Gentoo and I never had such an issue on my Intel X25-M G2
            ## VGA ##
            AMD: X1950XTX, HD3870, HD5870
            Intel: GMA45, HD3000 (Core i5 2500K)

              So they're using fstrim and a daily or weekly cron job.

              Does anyone know how Windows does it? I keep hearing that neither discard nor fstrim with a cron job are ideal (which was why there was such a long debate on whether or not to enable TRIM by default) and Windows does it completely differently but no one knows how.

                Linux could do that too. It only didn't because you didn't write required patches back in 2009. Linux is free mate, nobody is stopping you from adding support for anything.

                  Its actually funny cause according to: http://en.wikipedia.org/wiki/Trim_%2...system_support Linux had TRIM support before Windows did :P

                    Linux is free and is all about choice. Your comment assumes that my choice of paying for an expert to do it for me does not exist in the Linux world. I hope you will never use that 'argument' again.
