Script Preparation code:

var data = [];
for (var i=0; i<100000; i++) {
  data.push([Math.floor(Math.random()*10)/10, Math.floor(Math.random()*10)/10, Math.floor(Math.random()*10)/10]);
}

Tests:

nested
var ret = {}; for (var i=0; i<data.length; i++) { var d = data[i]; ret[d[0]] = ret[d[0]] || {}; ret[d[0]][d[1]] = ret[d[0]][d[1]] || {}; ret[d[0]][d[1]][d[2]] = true; }
combined
var ret = {}; for (var i=0; i<data.length; i++) { var d = data[i]; ret[d[0]+","+d[1]+","+d[2]] = true; }
