You were comparing select count(*) of a NDB table to a MyISAM table.  The  
MyISAM table is, of course, not in the cluster.  I was merely suggesting  
that if you instead compared it to an InnoDB table that was not in the  
cluster, the comparison would be more fair.

I don't think you can do either of these things.  Howewer, you might be  
able to trick mysqld into not using the count in the MyISAM table by  
adding a where clause that just happens to be true for all records.
