I just setup my first mysql cluster. It has three data nodes and three mysqld nodes running on three servers. Each server runs data and mysqld pair.
I test it with simple java application that makes inserts of 100 record batches to the single table in loop. I am getting 376 inserted rows per second when I run one thread. It is relatively slow comparing to 1874 records per second I got with single MySQL (not cluster) with InnoDB running on the same server with the same test. But my main problem is major (down to 25 records per second) throughput degradation when I add just one additional thread with it's own dedicated connection (running two threads in parallel with connection per thread).
Why is that?
