>
> If we write simultaneously to a large number of ledgers on a bookie, then
> performance drops significantly due to more seeks on the ledger device. In
> such cases, we should be clustering ledgers into files to reduce the number
> of seeks, and performing sequential writes on each file. Clustering ledgers
> will impact read performance, so we would to have a knob to control such a
> feature.
