That's empirically not true. I have disk caching in neoventi and it absolutely does help with the index as well, I can turn it off to prove it :) Not as _much_, but it does. Note that each cached block, in venti too IIRC, contains 8KiB. It contains several unrelated index buckets; something on the order of 250 index entries. That's enough to index nearly 1MiB. If you scan through 100MiB of data, we may well only do 100-200 disk reads from the index. It's not great, but it's not that bad. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tb88459bd8ed4d095-M49206b86f071469356ae9569 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
