  [https://issues.apache.org/jira/browse/HADOOP-1476 HADOOP-1476] adds to HBase 
{{{src/test}}} the script {{{org.apache.hadoop.hbase.PerformanceEvaluation}}}.  
It runs the tests described in ''Performance Evaluation'', Section 7 of the 
[http://labs.google.com/papers/bigtable.html BigTable paper].  See the citation 
for test descriptions.  They will not be described below. The script is useful 
evaluating HBase performance and how well it scales as we add region servers.

  This first test ran on a mini test cluster of four machines only: not the 
1768 of the !BigTable paper.  Each node had 8G of RAM and 2x dual-core 2Ghz 
Opterons.  Every member ran a HDFS datanode.  One node ran the namenode and the 
HBase master, another the region server and a third an instance of the 
!PerformanceEvaluation script configured to run one client.  Clients write ~1GB 
of data: One million rows, each row has a single column whose value is 1000 
randomly-generated bytes (See the BigTable paper for a better description).
