Yup, that's why we're working on it. Clearing data on quit won't get us there as data accumulates while browsing again and probably 90+% of the I/O happens while Firefox is running. > I also asked before (on the bugs) about more informations to the "journaled > storage" ... Great, but as I said we are working towards it. We don't know any details yet. > If it is - like I think - a lot of small files, I don't like it! Ok. > A lot of small files wast a lot of un-used bytes on the storage and brings a > big fragmentation to it! This significantly slows down a system! File systems have a lot of counter measures nowadays so that might not be as relevant anymore but I don't know for sure. We haven't decided on any journaled storage yet and we will be looking into multiple options, writing our own storage or taking an existing one. Performance and I/O will of course be important factors. - Tim _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
