Pete Wyckoff commented on HADOOP-4:
-----------------------------------
I just talked to one of our kernel guys and he isn't 100% sure as he hasn't
done that much IO stuff on Linux but thinks the 128K readahead may just be the
maximum.
we could always do like 1MB readaheads ourselves although that would complicate
things - although not that much since we could keep the cached data with the
open file handle so there's no dirty cache problems or garbage collection
issues since we just dump it when we do the close. So, maybe that's the easiest
way to go... I can probably look at that tomorrow or Thursday.
