FAQ
Hi all,

I start 5 small instances(1:NN, 1:BN, 3:DN) on Amazon EC2, and run my
benchmark:

1. Create 1000 files to hdfs at a time.
2. The file size is 1kb.
3. Run 20 times.

Benchmark results(throughput):

only NN NN+BN
Min. 51.26127 39.51181
Max. 57.70650 43.12806
Avg. 53.97225 41.38930 (ops/sec)

NN+BN taken: 24.1802130 ms per file.
NN taken: 18.5422298 ms per file.

Are the results reasonable?
Thanks.

Shen
