This test is more worrying for us. We can't even read 1000 reads per
second. Is there any limitation on cassandra, which will not work with
more number of columns ?.  Or mm I doing something wrong here?. Please
let me know.

I think you're mostly being limited by http://issues.apache.org/jira/browse/CASSANDRA-598
Can you try with a simple CF?
