> As servers get beefier, it makes less and less sense to have only a single thread do flushes at a time. In watching an insert-only benchmark run, HBase isn't currently disk, network, or CPU-bound -- it seems it's bound only by the rate at which flushes and compactions get processed. Increasing the threading a bit here should increase total disk/network throughput utilization.
