Hi Jeremy,Just because a file is in the cache now, it doesn't follow that it will be in the cache 5 minutes from now.
Sorry, it seems like I'm saying this a lot lately. Is it not true that
if the whole table will fit in [free] RAM, that the OS will cache the
file data and there is no need for a RAM disk. I don't really see how
performance would be any different than using a RAM disk. Either way,
you will still have the overhead of the filesystem calls, even if data
isn't actually read from disk, unlike with a HEAP table.
