Benchmarks
We ran benchmarks on a cluster of machines with:
- 2x Quad Xeon 2.5 Ghz
- 16GB RAM
- 4x 7200RPM Sata disks
- Gigabit ethernet
The benchmark we ran was NNThroughputBenchmark with a workload to create 200000 files. The number of threads was varied across the run, from 32 to 1024.
Each configuration was run 3 times and the average taken. The following configurations were used:

BookKeeper e3q2 | BookKeeper journal manager, with a ensemble of 3 and quorum of 2, each Bookie using separate disk for journal and ledger. |
BookKeeper e6q2 | BookKeeper journal manager, with a ensemble of 3 and quorum of 2, each Bookie using separate disk for journal and ledger. |
BookKeeper e3q2 1 disk | BookKeeper journal manager, with a ensemble of 3 and quorum of 2, each Bookie using single disk for journal and ledger. |
BookKeeper e6q2 1 disk | BookKeeper journal manager, with a ensemble of 3 and quorum of 2, each Bookie using single disk for journal and ledger. |
BookKeeper local (q1e1) | BookKeeper journal manager, with a single Bookie on the same machine as the namenode, using single disk for journal and ledger. |
