Pls send us your php code to see why paging didn't help. As for excel export of huge data, pls consider using Excel package's big spreadsheet export to reduce the amount of memory used, increase php excecution time as well. Rgds,

We received your report php code. You used Table widget with its paging but it only supports client-side paging. Thus, all of your data is still loaded to browser. I suggest using datagrid/DataTables widget with its server side paging:

With this, only data for the current page is loaded each time.
