How to load multiple grids faster

[eaglefox12]

I have 4 grid tables. They use the same modal. I cannot use the same store as each grid has to send a parameter value to get the data from db. So, what's happening is I ended up making 4 different stores and then when I load my application, it lags because it waits to load all the 4 stores. this is my grid.. so I have 3 more grids like this

this.grid1 =Ext.create('Ext.grid.Panel',{
        title:'GridView App',        store: store,        loadMask:true, 
        columns:[
            { header:'Q1',            sortable:true, dataIndex:'Q1', flex:1,},
            { header:'Q2',            sortable:true, dataIndex:'Q2', flex:1,},
            { header:'Q3',            sortable:true, dataIndex:'Q3', flex:1,},
            { header:'Q4',            sortable:true, dataIndex:'Q4', flex:1,}

and this is my store1... and similarly I have 3 more stores like this each with parameter Q2, Q3, Q4 respectively

var store1 =Ext.create('Ext.data.JsonStore',{
        storeId:'myData',        scope:this, 
        fields:[
            { name:'Q1', type:'int'},
            { name:'Q2', type:'int'},
            { name:'Q3', type:'int'},
            { name:'Q4', type:'int'}
        ],        
        sorters:[{            property:'Q1',            direct:'ASC'}],        
        proxy:{            
              type:'ajax',            
              url:'GridView/writeRecord',            
              extraParams: { ID: Q1 },            
              reader: newExt.data.JsonReader({                
                   root:'myTable',               
                   totalProperty:'count'
                })
            }
   });

Is there a faster/better way to implement it than the way that I have?

Perhaps you could load the store and filter for each grid:
