Re: Bad performance

 Hello everyone,

 I encountered a critical issue regarding MySQL cluster performance,

     My scenario is that I have 2000+ simultaneous updates, insertion and queries against MySQL database for every round operation,

   Without Cluster (1 MySQL Server), it took 15 mins to complete one round operation

With cluster (2 MySQL servers, two data nodes and 1 management server), it took much longer time (say, hours) to complete one round operation.
  So I am wondering if it is an known issue or there are any tuning tricks to improve it, any help is much appreciated  Many thanks
