I have json inventory inventory.json on the server like this:

[ { "body" : "SUV",
    "color" : { "ext" : "White diamond pearl",
        "int" : "Taupe"
      },
    "id" : "276181",
    "make" : "Acura",
    "miles" : 35949,
    "model" : "RDX",
    "pic" : [ { "full" : "http://images1.dealercp.com/90961/000JNBD/001_0292.jpg" } ],
    "power" : { "drive" : "Front wheel drive",
        "eng" : "2.3L DOHC PGM-FI 16-VALVE",
        "trans" : "Automatic"
      },
    "price" : { "net" : 29488 },
    "stock" : "6942",
    "trim" : "AWD 4dr Tech Pkg SUV",
    "vin" : "5J8TB2H53BA000334",
    "year" : 2011
  },
  { "body" : "Sedan",
    "color" : { "ext" : "Premium white pearl",
        "int" : "Taupe"
      },
    "id" : "275622",
    "make" : "Acura",
    "miles" : 40923,
    "model" : "TSX",
    "pic" : [ { "full" : "http://images1.dealercp.com/90961/000JMC6/001_1765.jpg" } ],
    "power" : { "drive" : "Front wheel drive",
        "eng" : "2.4L L4 MPI DOHC 16V",
        "trans" : "Automatic"
      },
    "price" : { "net" : 22288 },
    "stock" : "6945",
    "trim" : "4dr Sdn I4 Auto Sedan",
    "vin" : "JH4CU2F66AC011933",
    "year" : 2010
  } ]

here are two index, There are almost 5000 index like this. I parsed this json like this:

var url = "inventory/inventory.json";
$.getJSON(url, function(data){
  $.each(data, function(index, item){ //straight-forward loop
    if(item.year == 2012) {
      $('#desc').append(item.make + ' ' + item.model + ' ' + '<br/>' + item.price.net + '<br/>' + item.pic[0].full); 
    }         
  });
});

This is working fine.But the problem is that, this searching and fetching process is little bit slow as there are 5000 indexes already and it's increasing day by day. It seems that, it is a straight-forward loop to parse the data and a normal brute-force method.

Now I want to know if there any time efiicient way to parse more faster.Any faster method to parse instead of straight-forward loop ?
