Juhani Connolly commented on FLUME-1423:
----------------------------------------
I think this issue should be closed. The "fix" involved a loss of guarrantees
made by the file channel.
As is, the recommended methods for getting good performance are large batches,
and separating disks to allow for sequential writes. So long as each batch is
flushed before commit, there aren't going to be any silver bullets that will
result in huge performance boosts.
