PerformanceEvaluation much slower with 10k blocks

PerformanceEvaluation much slower with 10k blocks

My Setup:

3PC

1(quad 3GB MEM): HDFS Namenode + Datanode and HBase Master

2(2GB MEM) and 3: Datanodes + RegionServers

My Numbers:

PerformanceEvaluation with 1k data block:

random read - 254 / sec
random write - 873 / sec


PerformanceEvaluation with 10k data block:

random read - 63 / sec
random write - 83 / sec

Any comments?
