Benchmarking and Statistics for Hadoop Distributed File System

Does any body aware of any benchmarking of hadoop distributed file system?

Some numbers I am interested in are
- How long does it take for master to recover if there are, say, 1 million
blocks in the system?
- How does the recovery time change as the number of blocks in the system
change? Is it linear? Is it exponential?
- What is the file read/write throughput of Hadoop File System with
different configurations and loads?
