    Still a lot of speakers need to run through the video review! Please retweet and notify speakers about it. Check spam folder and take note that the review system takes two round trips: the first one for fixing times, the second one for releasing to the encoders.

    Yeah, that's the power of RDBMS like . Worked with it last 5 months. It's really amazing for complex queries and big/smart data. I wish app developers would learn some SQL instead of blindly using of ORM.

    There are no fadvise calls for seq scans (that actually hurts performance on Linux). See for simple test showing that.

    Odgovor korisnicima i sljedećem broju korisnika:

    Try tracing a largish btree scan that hits a lot of heap pages in random order. If you get a bitmap heap index scan, and if you set effective_io_concurrency to (say) 10, you'll see a bunch of posix_fadvise(POSIX_FADV_WILLNEED) syscalls (= prefetch hints to the kernel).
