Can you post the client code you're using to read/write from HBase?

 Hello there, I'm running a read/write benchmark on a huge data (tweeter
 posts) for my school project.
 The problem im dealing with is that the tests are going extreamly slow.
 I dont know how to optimize the process. Hbase is using only about 10% of
 RAM memory, and 40% of CPU.
 I've been experimenting with properties of hbase-site.xml file but I can't
 see any results. I think there is something I need to put in the API's code.
 It's a single node, local operation. Virtual machine has 8GB RAM. Any help
 will be appreciated.

Have you looked at the performance guidelines in our online book?
