Yes, we just haven't done that internally in any official way... >> There might still be some surprises caused by the performance >> differences between ext3 and ubifs, or between the OneNAND and the >> eMMC. > > For previous devices it felt faster when booted from card except some > corner cases (frequent fsyncs in sqlite causing metalayer-crawler to > take ages). Yes, fsyncs on ext3 (in Tracker and elsewhere) is what I am mostly worried about right now. People here have brought up the idea to have a small partition on the OneNAND specifically for database journals. Maybe mounted on /var/journals? > And BTW when OneNAND is free, in theory it could be used for swap (over > ubi) causing less writes to eMMC when system is out of memory and > already slow. Yes, that's the plan. (Don't know the details of how swap will be put on a mtd, though, but I am confident that our kernel guys will dtrt.) _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
