while dhtmlxSpreadsheet load large data

Hi, I’m new about dhtmlxSpreadsheet, I try to create a spreadsheet object on web page. Everything goes well.
But if the spreadsheet with large data (about 1000 rows, and 100cols), the “dhx_sh.load()” method goes slow,
I think the reason maybe everythings initial with client side (browser, with javascript), not on server side.

How can I make it faster with large data.
Thanks.

Both grid and spreadsheet are optimized for long dataset and works not so well when you have a structure with big number of columns.
Unfortunately, there is no an easy fix.
