Hi Daniel,

   I have 4 nodes in my cluster, and run a benchmark on node A in Java.
  P.S. Replication = 3

Hi Ching

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

Anyways congrats on getting better results :-) .

Hi all,

  I run a benchmark with my own code and found that the 100000 inserts performance is better
than others, Why?
 Can anyone explain it?
