Ubuntu Wants To Enable SSD TRIM By Default

Posted by Soulskill on from the getting-into-fighting-trim dept.

jones_supa writes "During the first day of the latest virtual Ubuntu Developer Summit, Canonical developers finally plotted out the enabling of TRIM/DISCARD support by default for solid-state drives on Ubuntu 14.04. Ubuntu developers aren't looking to enable discard at the file-system level since it can slow down delete operations, so instead they're wanting to have their own cron job that routinely runs fstrim for TRIMing the system. In the past there has been talk about the TRIM implementation being unoptimized in the kernel. Around when Linux 3.0 was released, OpenSUSE noted that the kernel performs TRIM to a single range, instead of vectorized list of TRIM ranges, which is what the specification calls for. In some scenarios this results in lowered performance."

    More like Linux doesn't follow the best practice recommendations of the standard when it wouldn't be all that hard to do so.

    I imagine that discussing the suggestions on Slashdot first is a way to avoid presenting half-baked suggestions to busy developers.
