Subject Re: Question about Insert Time with multiple node
Date Wed, 16 Dec 2009 14:45:36 GMT
Sounds like you are using a single thread, so the increased latency is
artificially reducing your numbers.  Add more threads (stress.py uses
50 by default) to get more throughput. (Also true even for a single
node, but more noticable when you add network overhead to the
cluster.)
