request to iss from jquery

I have page which has a grid section.
User can select one record from it and its details loads up in the details section

Now under details section information comes from three tables.
I am using Jquery ajax method to load the information in the form of json.

my question is, as I need information from three tables then
1. should I make one request and get the big bulky object in return.
2. should I make multiple request and get multiple response but smaller in sizes.

Save server bandwidth and resoruces doing one request

{
    table1: [results request 1]
    table2: [results request 2]
    table3: [results request 3]
}

Depends on the size and type of the individual responses.

If the response size is relatively small (less than 100 KB) in total and response time is less than 10 sec, then one response is best.

However, if three individual queries on database you have fired are heavy/slow then it makes sense to call them one by one. You can show waiting indicator to manage the user experience or ensure that it is not too bad.

my problem is that in one of the table I have memo field and user can copy and paste any amount of data in it.
So the request size can vary.

but I also think doing a separate request would be better

In that case, unless you can stream data from your server, don't fetch everything in one go.

separate requests :
- slow dow, the proces
- consume bandwith
- slow down server (more request)

if you want to increase user experience choose another method
choosing a solution because it's easiest is not a right choice IMHO
