Data handling limit of Auto Complete widget

Hi,

I am using jQuery UI Autocomplete 1.8.23 widget for my webpage. My source of words are on a Database and I wrote some Java classes to fetch it through POST calls. When the data is more (such as 4000 terms or around 250KB), the widget is very slow. If the data further increases (to 10,000 terms), the performance is much worse. I have tried in both JSON as well as Array formats and ended up with same result. Following is my code snippet:

$.post(

"./getAutoCompleteResults.html",{

searchKey: inputString,

function(datas) {

if(datas != ''){

availableTags = datas.split(',');

$( "#inputBox" ).autocomplete({

source: availableTags,

minLength: 3

});

}

}

);

I wanted to know if there is any limit with the widget in handling bigger data with more number of results/terms. Also, please let us know if there is any other way to handle such bigger data on Auto Complete widget.

Thank you.

Regards,

Uma Shankar
