I have a jqGrid on a web page, with large data sets. Up to 100 rows (in XML format) are sometimes sent to the browser at a time. On IE8 the combined effect is a noticeable delay.
Will changing the data source to JSON (instead of XML) have a measurable effect in these conditions?

Note: I know this is an IE specific problem. On Chrome I get an instant response on the same page. But I'm currently targeting IE8 :(

JSON has native support in JavaScript, so in the most cases the working with JSON is more quickly. Moreover, the size of JSON response from the server are smaller as the corresponding XML response. So I would recommend you to switch to JSON.

Nevertheless in many cases the real jqGrid example can has more other performance bottlenecks which independent on the data format. Moreover you can also choose different implementation in JSON which represent your data. So the best recommendation one could get you if you append your question with the current jqGrid definition, define which is the best id for the data row and post the test XML data.

UPDATED: Look at some old answers about jqGrid performance optimization: this, this and this.

    @Ron Harlev: I added some additional links about performance optimization in jqGrid. Moreover I repeat my suggestion to try optimize your current code of jqGrid. If you append your question with the code or post the URL, I could look inside the code and probably give you some recommendations based on the code. – Oleg Jan 06 '11 at 08:14
