Hi Ching

You are inserting using php,perl,python,java or ? and is cassandra installe=
d locally or on a network system and is it a single system or you have a cl=
uster of nodes. I know I've asked you many questions but the answers will h=
elp immensely to assess the results.

Anyways congrats on getting better results :-) .
