To recreate with the mongo shell:
pre = function( collection ) {
collection.drop();
var docs = [];
for ( var i = 0; i < 4800; i++ ) {
docs.push( { x : 1 } );
docs.push( { x : 2 } );
docs.push( { x : 3 } );
}
collection.insert(docs);
collection.ensureIndex( { x : 1 } );
};
use test0
pre(db.test)
benchRun({"ops":[{"op":"command","tags":["distinct","command","core"],"ns":"test0","command":{"distinct":"Commands_DistinctWithIndexAndQuery0","key":"x","query":{"x":1}},"safe":false,"w":0,"j":false,"writeCmd":true}],"seconds":5,"host":"127.0.0.1:27017","parallel":8})
